Voice and Video Calls

Conversation and Phone Environments Require Microsoft Exchange Web Services

Issue:

Two new top-level Lync 2010 environments, the Conversation Environment and the Phone Environment, work correctly only if Exchange Web Services (EWS) is enabled on the Exchange Server.

If EWS is not available, the following occurs:

Resolution: There currently is no workaround for this issue.

Audio or Video Device Detection Fails on Windows Vista if the User Plugs the Device into a Different USB Port

Issue: If a user selects a device as the preferred audio or video device for conversations using Lync 2010, and then detaches the device and plugs it into a different USB port, Lync 2010 may not recognize it because Windows gives it a different name. This issue is limited to Windows Vista.

Resolution: The user can reattach the device to the port to which it was originally attached.

Reverse Number Lookup (RNL) Randomly Resolves to a Contact When There Are Multiple Contacts with the Same Phone Number

Issue: The display name that appears for an incoming call in the pop-up alert or conversation window may be incorrect when there are multiple Global Address Library (GAL) and/or Outlook contacts that have the same phone number.

Resolution:

There currently is no workaround for this issue.

Limitations on Detection of Phone Numbers in Web Pages

Issue:

For this release, phone number detection on Internet Explorer Web pages is not enabled in the following cases:

Resolution:

There currently is no workaround for this issue.

Release Limitations of Remote Call Control (RCC) Support

Issue:

For users who are using Remote Call Control (RCC), Lync 2010 will not support the following features:

Resolution:

There currently is no workaround for this issue.

User Cannot Open a Voice Mail Message in Virtualized Outlook 2010 Using Lync

Issue:

A user cannot open a voice mail in message in virtualized Outlook 2010 using Lync.

Resolution:

Open the message directly in Outlook.

Web Search Is Not Supported for RCC Users

Issue: Remote Call Control users will not support Web Search.

Resolution: Remote Call Control users should be provisioned with GAL download, and not Web Search.

You Cannot Update Call Forwarding Rules in Previous Versions of Clients and Devices After Upgrading One of the Clients to Lync Client 2010

Issue:

After you upgrade to any Lync 2010 client or device, you cannot update your call forwarding rules from your other clients and devices. This issue will not occur if you've only upgraded to Lync Server 2010 on the back end, and none of the user's clients or devices are upgraded to Lync 2010.

Resolution:

Upgrade all your Lync client or device endpoints at the same time. If that is not possible, you can change your call forwarding rules in your upgraded Lync 2010 client or device.

Running Lync 2010 Using Two (or More) Different Accounts on the Same Computer Causes Confusion When Making or Receiving Calls

Issue:

If you place a call using your audio device while running Lync 2010 using two different accounts (on the same computer), the call recipient receives call alerts from both accounts. 

If you answer a call on your audio device while running Lync using two different accounts (on the same computer), you may hear a continuous dial tone (which will subside in a few seconds) after the call is answered.

Resolution:

Exit the instance of Lync running the inactive account.

Lync Stops Responding When Playing Sounds on Computers Running Windows 7 or Windows Vista

Issue: You are running Windows 7 or Windows Vista, and Lync stops responding when playing sounds.

Resolution:

This results from a Windows issue. Please install the following hotfix: http://support.microsoft.com/kb/981679

Sharing and Collaboration

You May See Black Squares or Other Display Problems When Viewing a Shared Application

Issue:

You may see black squares or other display problems when viewing a shared application.

Resolution:

You can mitigate this by switching to a scaled view if you are viewing the application at a 1-to-1 ratio, or switching to the 1-to-1 view if you are in a scaled view.

Viewers of Shared Application See a Black Window

Issue:

In a Lync meeting, if a participant is sharing an application or window that cannot be set to layered, for example a Command Prompt window or some versions of Windows Media Player, and another non-shared window completely covers the shared window, the other participants will see a black window. Even partial overlap will cause users to see a black window (in addition to the originally shared window).

Resolution: The participant who is sharing should bring the shared application window to the top, and make sure that none of it is being covered by another window.

During Sharing Session Meeting Participants See Previously Presented Content

Issue:

If Presenter A begins sharing a PowerPoint presentation or whiteboard and then leaves the meeting without clicking Stop Presenting, and then Presenter B begins sharing an application, two issues can occur:

  1. Presenter C joining the meeting will cause the application sharing session of Presenter B to end.
  2. Once the application sharing session of Presenter B ends, either due to number 1 above or because the presenter intentionally stopped sharing, people who are already in the meeting will see nothing presented, but newcomers to the meeting will still see Presenter A's PowerPoint presentation or whiteboard.

Resolution:

Presenter A should click Stop Presenting before leaving a meeting. (This would prevent the problem from occurring.)

Presenter B should restart his or her sharing session (if it stops due to Presenter C joining the meeting).

Optionally, Presenter B could share the PowerPoint presentation or whiteboard again, and then click Stop Presenting.

When Sharing Word During a Lync 2010 Meeting, Some Drop-Down Boxes May Not Be Visible to Viewers

Issue: When sharing Microsoft Word during a Lync 2010 meeting, some drop-down menus, tooltips, and combo boxes may not be visible to the viewers.

Resolution: Switch from program sharing to desktop sharing.

Application Sharing Scenarios That Are Not Supported in Lync 2010

Issue:

In addition, the sharing of Windows Media Player in skin modes is not recommended because it results in a less than optimal user experience.

Resolution:

The user should share their desktop.

Note:  A remote desktop session can be shared as an application from the local computer.

Shared Content May Appear Monochrome If the Presenter's Computer Is Running Outdated Graphics Drivers

Issue:

If the presenter's computer is running outdated graphics drivers, the shared content may appear monochrome to the viewers.

Resolution: The presenter should update their graphics drivers.

Viewing Shared Content May Be Sub-Optimal in Office Communicator 2007 R2 When Presenter Is Running Lync 2010

Issue:

When the presenter is running Lync 2010, meeting participants who have not upgraded their client can still see the shared programs or desktop. However, if the shared material is much smaller than the screen of the presenter (for example, if the presenter has multiple monitors), the viewer will see a large black space representing the unshared area.

Resolution:

The viewer can upgrade to Lync 2010.

Alternatively, the presenter can share a monitor or desktop, or maximize the shared window so that the non-shared area is minimized.

Windows Prompts You to Switch to Basic Color When You Share Your Desktop

Issue:

Windows prompts you to switch to basic color when you share your desktop. This may happen if your computer is low on memory, or if the video drivers are outdated.

Resolution:

Try closing other processes that may be consuming memory, and update the video drivers.

If the issue persists, consider switching to basic color when sharing your desktop.

Pressing the Enter Key in the Attachments Dialog Box Does Not Save the Content

Issue:

When you try to select the Save As or Save with Annotations option in the Attachments dialog box by pressing the Enter key, the content is not saved. This is true for content items that are available in the content bin as well as attachments.

Resolution:

Use your mouse to select the appropriate menu option.

Audio and Video Files Embedded in a PowerPoint Presentation Cannot Be Played in a Lync Meeting

Issue:

Audio and video files that are embedded in a Microsoft Office PowerPoint presentation cannot be played when you share the presentation in a Lync meeting.

Resolution:

There currently is no workaround for this issue.

Lync 2010 User Appears as "Guest" in a Meeting Hosted by a Non-Federated Server

Issue:

When a person using Lync 2010 joins a meeting that is hosted by a non-federated server, the person is listed as "Guest" in the meeting roster.

Resolution:

There currently is no workaround for this issue.

Excel Cannot Be Shared from a Remote Computer

Issue:

If you are working on a remote computer and initiate a Lync 2010 meeting, you cannot share Microsoft Office Excel with meeting attendees.

Resolution:

To work around this issue, share your desktop instead of the application.

Aero Turns Off When You Begin Sharing an Application

Issue: When you initiate an application sharing session in Lync, the screen flickers, Windows Aero is turned off, and you receive the following message: "The color scheme has been changed to Windows 7 Basic." This does not occur when you share your desktop rather than an application.

Resolution:

Aero is restored to its original state when sharing stops.

When a Meeting Recording Is Exported to a SharePoint Site and Played from Windows 7 Using Internet Explorer 8, the Media Player Cannot Be Started from the Browser

Issue:

When you export a meeting recording to a SharePoint site and play it from Windows 7 by using Internet Explorer 8, the browser cannot start the media player. Users are not able to play the WMV recording.

Resolution:

Update Windows manually by using the following steps, or see http://go.microsoft.com/fwlink/?LinkId=185215 for Knowledge Base article KB974431.

1.  Close all instances of Internet Explorer.

2.  Click Start and then click Default Programs.

3.  Click Set program access and computer defaults.

4.  Select Custom and then click the double down arrow to display the configuration options.

5.  Under Choose a default media player, select Windows Media Player.

6.  Click OK.

7.  Restart Internet Explorer and try the links again. Internet Explorer should open the file in Windows Media Player.

You Cannot Grant Control of an Application That You Are Running with Administrator Privileges

Issue:

In a Lync meeting, you cannot give control of an application to another presenter if the following are true:

Resolution:

Run Lync with administrator privileges.

Alternatively, you can grant control of your desktop to the other presenter.

Lync in a Citrix Environment Stops Responding When Users Attempt Desktop Sharing

Issue:

When you run Lync on Citrix Xenappserver and try to use desktop sharing, Lync stops responding.

Resolution:

There currently is no workaround for this issue.

Content from Previous Meeting Might Be Available to Participants in an Organizer's Second Default Meeting

Issue:

When a meeting organizer schedules back-to-back online meetings using the default meeting options, participants in the second meeting may have access to content (PowerPoint files, whiteboards, polls) that were shared during the meeting organizer's previous meeting.

Lync 2010 makes all content "organizer only" when the last presenter leaves a meeting that is scheduled with default meeting options. However, if participants join the second meeting before all presenters have left the first meeting, these new participants will have access to content from the previous meeting.

Resolution:

The organizer or any presenter can select End and Exit Meeting when the first meeting ends. This ends the meeting for all participants, so Lync 2010 makes all content "organizer only" and therefore unavailable to participants of the second meeting.

Alternatively, the organizer can manually hide all content from meeting participants by choosing Make Available To - Organizer for each item in the meeting Content List.

Cause: The Online Meeting Add-in for Lync 2010 located the account owner's SMTP from Exchange but could not locate the SIP address, either from Exchange or from Lync 2010. You may have signed in to Lync 2010 and Outlook using different accounts.

Response: Contact your Lync administrator.

 

Message: The person you are acting scheduling on behalf of is not UC enabled or there may be issues with this person's Lync Server account. Make sure you are signed in to the same account you use for Microsoft Outlook. If the problem continues, please contact your support team.

Cause: The Online Meeting Add-in for Lync 2010 located from Exchange the SMTP of the person for whom you are scheduling but could not locate the SIP address, either from Exchange or from Lync 2010. You may have signed in to Lync 2010 and Outlook using different accounts.

Response: Contact your Lync administrator.

 

Message: Microsoft Exchange is unable to find the email of the person you are acting on behalf of. Please contact your support team.

Presence and IM

Sporadic Presence Indication Failure for Lync Users

Issue:

Lync users may occasionally see "Presence Unknown" for themselves or other people. This is more likely to occur when a user first signs in to a Lync deployment.

Resolution: Sign out of Lync and then sign back in.

Some Lync Buttons for Interacting with a Contact or Changing Contact Display Options May Incorrectly Appear Unavailable

Issue:

Certain buttons on the contact card that appears when you point to a person's picture in Lync, as well as the display-related buttons above your contact list, may appear to be unavailable although they are actually available. This is because the buttons are set to a partially opaque state.

The following buttons exhibit this behavior:

Resolution:

There currently is no workaround for this issue.

Office Integration

Outlook Integration With Lync 2010 Will Not Work If Office Runs Under Lower Privilege Than Lync

Issue: If Lync is running under a higher privilege than Outlook, Outlook integration features such as presence and conference scheduling may not work. This is because the lower privilege under which Outlook is running will not be able to create a proxy for the out-of-process Lync COM server running under a higher privilege.

Resolution: Check the User Account Control settings, lower the privilege under which Lync is running, and then restart Lync.

Miscellaneous

Lync 2010 Attendee Process Starts When Internet Explorer Is Started

Issue:

The Attendee process starts automatically when Internet Explorer starts, and it causes Internet Explorer to slow down.

Resolution:

Follow these steps to work around this issue:

  1. Open Internet Explorer.
  2. Click Tools, and then click Manage Add-ons.
  3. Select the Lync 2010 Attendee add-on, and click Disable.
  4. Click Close.

Default Security Settings on Windows Vista and XP Prevent Lync From Signing In Using NTLM When Minimum Session Security Requires 128-Bit Encryption on Lync Server

Issue:

Windows Server 2008 R2 has changed the default setting for NTLM minimum session security to require 128-bit encryption. By default, 128-bit encryption for NTLM authentication is disabled in Windows Vista and Windows XP SP3. As a result, unless this setting is harmonized between the client and Lync Server, NTLM authentication will fail. This may result in users receiving the following error message: "Cannot Sign in to Lync: Lync was unable to sign in. Please verify your logon credentials and try again..." In this case, the client logs reveal only that the SIP registration request was rejected with a 401 response.

This is particularly important for external clients as Kerberos is not available externally.

Resolution:

It is currently recommended that for desktop clients, the settings be harmonized. For more information, see "Network security: Minimum session security for NTLM SSP based (including secure RPC) clients" at http://go.microsoft.com/fwlink/?LinkId=187784.

If this is not possible, 128-bit NTLM encryption must be disabled on the server.

Unsaved PowerPoint Presentation Is Lost When You Put Your Computer into Sleep Mode

Issue:

If Lync 2010 is installed on your computer and you have an unsaved PowerPoint presentation, and then you put your computer into sleep mode, PowerPoint will close and your presentation will be lost when you wake your computer.

Resolution:

To avoid losing your presentation, save it before putting your computer to sleep.

Another option is to disable the Lync add-in in PowerPoint:

1.    On the File tab in PowerPoint, click Options, and then click Add-Ins.

2.    At the bottom of the Add-ins dialog box, in the Manage box, make sure that COM Add-ins is selected, and then click Go.

3.    In the COM Add-ins dialog box, clear the Lync Collaboration Add-in check box and then click OK.

The Collaboration tab in PowerPoint will be disabled, but no other PowerPoint functionality will be affected.

Custom Sound File Does Not Play in Lync 2010

Issue: After a user selects a custom sound to be played by Lync 2010, Lync does not play the sound. The most common .wav files have a WAVEFORMTEX format. However, there is a WAVEFORMATEXTENSIBLE format that supports higher quality sound and more channels. Lync 2010 does not support the WAVEFORMATEXTENSIBLE format. Files with the WAVEFORMTEX and WAVEFORMATEXTENSIBLE format have the same extension (.wav), so the user cannot distinguish them by looking at the filename.

Resolution: There is currently no resolution. Users must select .wav files that do not use the WAVFORMATEXTENSIBLE format.

Lync 2010 Is Incompatible with Previous Versions of Office Communications Server

Issue: Lync 2010 users who are logged on to an Office Communications Server 2007 R2 computer or Office Communications Server 2007 computer may see incorrect behavior. 

Resolution: Do not use Lync 2010 with previous versions of Office Communications Server. Use Lync 2010 only to sign in to Lync Server 2010.

End Users Cannot Opt Out of SQM If Administrator Enables the Policy

Issue:

If the system administrator enables Software Quality Metrics (SQM) by using in-band setting "EnableSQMData", end users cannot opt out of the program, and the user interface is misleading.

When a user tries to opt out of the Customer Experience Improvement Program (as SQM is called), the user has the option to click OK. However, when the user returns to the Options dialog, the user interface indicates that the user is participating in the program.

Resolution:

The administrator should disable SQM if end users do not want to send information to Microsoft.

Note: SQM is disabled by default.

When Lync or Lync Attendant Is Running, You Cannot Use Alt+Ctrl+M Keyboard Shortcut for Any Other Program

Issue:

When you are running Lync 2010 or Lync Server 2010 Attendant, you cannot use the keyboard shortcut Alt+Ctrl+M for any other program. This is because the keyboard shortcut brings up the Lync "debugUI" interface.

When you are not running Lync or Attendant, you can use Alt+Ctrl+M in other programs such as OneNote, Word, or Outlook.

Resolution:

There currently is no workaround for this issue. It will be fixed for the final release candidate. Please use a different procedure to accomplish the task, or temporarily exit Lync.

Notes:
In Word , Alt+Ctrl+M is used to add comments to a document. With Lync running, you can click the Review tab and then click New Comment.
In OneNote, Alt+Ctrl+M is used to move or copy pages. With Lync running, you can right-click the page tab and then click Move or Copy.

Lync Web App

When Scrolling in JAWS Screen Reading Software, Items Are Skipped

Issue:

When using JAWS screen reading software, if you scroll down or up, some of the items in the list are skipped because the control jumps multiple items.

Resolution: This is a known limitation in JAWS. Disable the Access key in JAWS to resolve this issue

 

Lync Web App Does Not Respond to Changes in the Browser Zoom Setting

Issue: When the browser zoom setting is increased or decreased, Lync Web App does not respond.

Resolution:

Due to Silverlight limitations, the current release does not support browser zoom settings.

Cannot Install Lync Web App Plug-in on a Computer Running Windows Server

Issue:

On Windows Server 2008 R2, Windows Server 2008, and Windows Server 2003, you can't install the Lync Web App plug-in.

Resolution:

Try disabling the Do not save encrypted pages to disk option:

  1. In Internet Explorer, click Tools and then click Internet Options.
  2. On the Advanced tab, check whether the Do not save encrypted pages to disk option is enabled (it is enabled by default on server computers).
  3. Disable this option to successfully download and run the Lync Web App plug-in installer.

If this does not work, you may also need to change the default security settings. Please see the following article for instructions on how to change these settings:
http://msdn.microsoft.com/en-us/library/aa368304(VS.85).aspx

UAC Error While Installing Lync Web App Plug-In

Issue:

In Windows Server 2008 and Windows Vista with SP2 or earlier, when you try to install the Lync Web App plug-in the process fails and you receive a "UAC" error.

Resolution:

Make sure that UAC is turned on, and then try installing the plug-in again.

Using MS Pinyin (SimpleFast Style) to Enter Chinese Characters in Lync Web App Causes the Program to Stop Responding

Issue:

When you use MS Pinyin (SimpleFast style) to input Chinese characters in Lync Web App, the program stops responding.

Resolution:

This is a Silverlight issue that has been fixed. Please upgrade to Silverlight version 4.0.50723.0 or a later version.

Lync Web App Disappears From View When Empty Stage Is Hidden in Full-Screen Mode

Issue:

Issue:

In projects created using the UC WPF Application template, Microsoft.Office.Uc.dll is not copied to the debug output directory. As a result, no Lync 2010 controls are correctly initialized. Also, the control's UcConnectInitializationError property contains an exception object with the following inner exception message:

"Could not load file or assembly 'Microsoft.Office.Uc, Version=4.0.7246.504, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified."

Lync Controls for Silverlight Require That Internet Explorer Protected Mode Be Turned Off

Issue:

The Silverlight controls in the Lync SDK cannot establish the required connection to Lync when Internet Explorer Protected Mode is enabled. 

Resolution:

Lync Controls Class Library Documentation References Namespaces and Classes That Are for Microsoft Internal Use Only

Issue:

The Lync SDK documentation found in LyncClientSDK.CHM contains class library reference documentation for the Lync Controls that documents namespaces and classes that are not intended for use by developers.

Resolution:

Documentation found in the section labeled "Lync Controls Class Library" should be disregarded with the exception of the specific set of classes identified in this release note.

For this release, these are the only classes that should be used by developers:

Localization

Uninstalling the Multilingual User Interface (MUI) Package Deletes Some Microsoft Lync 2010 Resource .dll Files

Issue:

Uninstalling the Multilingual User Interface (MUI) package deletes some Microsoft Lync 2010 resource .dll files. Deleted resource files affect the Online Meeting Add-in for Lync 2010 and Recording features after the MUI package is uninstalled.

Resolution: After uninstalling the MUI package, run auto-repair to repair the affected features.

Microsoft Lync 2010 Recording Player Displays the Previous Localized Language When You Install a Different Version of Microsoft Lync 2010

Issue: When you install Microsoft Lync 2010 with a different language after you uninstall a localized language of Lync, you see content in the previous language in Microsoft Lync 2010 Recording Player instead of the language you just installed.

Resolution: Manually remove the file %AppData%\Microsoft\Communicator\Recording Player\playback.xap, and then restart Microsoft Lync 2010 Recording Player.

Lync Web App Available Languages Are Not Installed During Lync Server 2010 Setup

Issue:

The languages available for Lync Web App are not installed during Lync Server 2010 setup.

Resolution:

To add additional supported languages for Lync Web App, you need to install webcomponents.msp.

Issue: Due to technical limitations, localized content and Help files cannot be provided online for the Catalan release of Microsoft Lync 2010.

Resolution:

Users will be directed to Spanish product documentation and Help files at Office.com.

Note: The referenced user interface strings and screenshots in the Spanish content may differ from the Catala user interface.

Enterprise Voice

Administrators Should Not Set TTY Mode in Conference Phones

Issue:

When administrators set TTY mode in conference phones, calls have echoes because TTY mode disables the acoustic echo cancelling (AEC) in the device. Setting this mode may also cause other audio issues.

Resolution:

Administrators should not set TTY mode in conference phones.

Lync Users Cannot Place Calls Using Exchange Auto Attendant Without Exchange Server 2010 SP1

Issue: When a Lync user tries to place a call to another Lync user through an Exchange auto attendant, the call fails unless Microsoft Exchange Server 2010 SP1 is the server for the Exchange auto attendant.

Resolution:

Administrators should upgrade to Exchange Server 2010 SP1 if they wish to enable this scenario.

Cannot Add IM to an Anonymous Response Group Call to a Work Phone Number

Issue: A Lync Server 2010 Response Group agent making a call on behalf of a response group cannot add instant messaging to an anonymous conversation if the call was placed to a published Work phone number. The Work phone number is used by default when you double-click a contact to make a call using Lync 2010 Attendant.

Resolution: To be able to add the IM modality to an anonymous call, a Lync Server 2010 Response Group agent must start the call on behalf of the response group by making a Lync call.

Devices

Text Telephone (TTY) Mode Should Not Be Used on Polycom CX3000 Phone

Issue: Although the Text Telephone (TTY) mode setting is available on the Polycom CX3000 phone, enabling this mode causes echoes during calls. This is because the Acoustic Echo Cancellation (AEC) is disabled when TTY is used.

Resolution: The only workaround is to not use the TTY mode.

Presence Status of Common Area Phone Accounts Is Not Valid

Issue: Presence status appears for Common Area Phone accounts. This could lead to confusion for remote parties.

Resolution: The presence status should be ignored. Viewing presence for Common Area Phone accounts cannot be disabled.

Headset Volume Settings Are Not Applicable for Polycom CX500 and Aastra 6721i Phones

Issue: Headsets are not supported on Polycom CX500 and Aastra 6721i phones. Although the Lync Settings screen displays a headset volume control for these devices, changes made to this control have no effect.

Resolution:

There is no workaround for this issue.

For Polycom CX500 and Aastra 6721i Phones, the Speaker Phone Cannot Be Used to Send Audio

Issue: For Polycom CX500 and Aastra 6721i phones, if the user selects the speaker as the active audio device, the user can only listen to remote-party audio. Audio generated by the local user will not be transmitted to the other parties in the conversation. No indication is provided to the user that only one-way audio is available.

Resolution: There currently is no workaround for this issue. On these phones, users can select the speaker phone option to listen to calls, but not to engage in conversations.

Call Forwarding Is Not Available for Common Area Phone Accounts

Issue: For Common Area Phone accounts, the call forwarding interface is not displayed even if AllowCallForwarding is set to true in the voice policy.

Resolution: There is no workaround for this issue. The call forwarding enabling and disabling interface will not be made available for Common Area Phone accounts, so the AllowCallForwarding policy setting will not have any effect.

On-Phone Help Content Is Not Relevant to Common Area Phone Accounts

Issue: The on-phone Help content is for Information Worker accounts. Common Area Phone accounts have limited functionality. As a result, much of the on-phone Help content is not applicable to Common Area Phone accounts.

Resolution: There is no workaround. The content will always be displayed. Users should only consult the Help content for features they see available on the phone.

Audio from Several Parties May Not Be Heard in Multiple Call Scenario

Issue:

In Microsoft Lync 2010 Phone Edition, if the phone is ringing with an incoming call and another call is made or accepted, audio from only one party may be heard in the second call.

Resolution:

There is no current workaround for this issue. The user must terminate the call and then re-establish it.

It Is Possible to Select Headset Audio Mode Even If There Is No Headset Connected to the Device

Issue:

It is possible to select headset mode on a Lync 2010 Phone Edition device even if there is no headset connected to the phone. In this case, if a call comes in and the user answers it using the Answer soft key on the phone user interface, the call is answered and audio is routed to the headset port. However, since there is no headset attached, there is no audio.

Resolution:

After the call  has been answered, switch the audio mode by pressing the hands-free hard key or picking up the handset. This routes the audio to the newly selected mode, and the user will be able to send and receive audio.

Lync 2010 Phone Edition Image Update Failures Due to NAND Memory Errors/Problems

Issue:

There are two types of NAND memory errors/problems that can lead to image update failures:

Resolution:

For the first problem (0x70/200 code), perform a hard reset (turn the phone on while pressing the * and # keys). This clears the file system and allows the image update process to complete successfully on the next attempt.

For the second problem (0xd/200 code), install Cumulative Update 1 (CU1).

After an Audio Mode Is Selected, Switching Audio Modes Does Not Answer an Incoming Call

Issue:

If the user selects the hands-free or headset audio mode, or takes the handset off the hook, and then receives an incoming call, the call can only be answered using the device user interface by pressing the Answer soft key. In this scenario, switching audio modes while the device is ringing will not answer the call.

Resolution:

There is no workaround. This scenario is working as designed.

In USB Paired Mode, Device Volume Does Not Affect Computer Volume

Issue:

When a Lync 2010 Phone Edition device is paired with a computer over USB, adjusting the volume on the device does not affect the volume setting on the computer.

Resolution:

There is no workaround. This scenario is working as designed; computer volume changes should be made on the computer.

USB Host Controller on Lync 2010 Phone Edition Devices Is Not Active

Issue: The USB host port on Lync 2010 Phone Edition devices is not currently functional and is reserved for future use.

Resolution:

Not applicable.

Network Pass-Through Mode Resets When a Device Restarts

Issue:

When a Lync 2010 Phone Edition device restarts, the network Pass-Through mode also resets, and there is a momentary interruption in the Ethernet connection between the device and the computer to which it is connected.

Resolution:

Not applicable.

Lync 2010 Phone Edition Supports a Maximum of Eight Calls at a Time

Issue:

Lync 2010 Phone Edition supports up to eight calls at a time; one of these calls can be active, and the rest are on hold. When this maximum is reached, it is not be possible to make a new call, accept an incoming call, or join a conference.

Resolution:

There currently is no workaround for this issue.

PIN-Based Authentication on Polycom CX600, Polycom CX500, Aastra 6725ip, and Aastra 6721ip, Running Lync 2010 Phone Edition, Only Works for Deployments with One SIP Domain

Issue:

PIN-based authentication requires the user to enter the telephone number or extension and PIN on the phone. The phone then issues a  "DHCP Options 120" query to determine the Lync Server 2010 pool FQDN to connect to. However, the pool FQDN must match the user's SIP domain for security purposes. Also, this mechanism will work only for one SIP domain in the current release.

Resolution:

There currently is no workaround for this issue.

Desk Phones Running Lync 2010 Phone Edition Continuously Restart If User Signing In Has Large Number of Outlook Contacts

Issue:

If there are more than (approximately) 1,000 contacts  in any Contacts folder (other than the  SenderPhotoContacts folder), processing those contacts takes a lot of time just after signing in. This blocks certain key operations on the desk phone and a watchdog time-out is triggered, which causes the phone to restart. This issue will occur every time the user automatically signs in to the desk phone after it restarts.

Resolution:

Reduce the number of contacts as much as possible, preferably below 500. This will prevent the watchdog time-out from triggering while the contacts are being processed.

 

Note: A solution not requiring a reduction of contacts will be provided in a later release of the product.

PIN-Based Authentication on Polycom CX600, Polycom CX500, Aastra 6725ip, and Aastra 6721ip, Running Lync 2010 Phone Edition, Only Works Within the Internal Enterprise Deployment

Issue:

Desk phones provisioned using PIN-based authentication will not work from outside the network if the external DNS SRV records point to an Office Communications Server 2007 or Office Communications Server 2007 R2 Access Edge Server.

Resolution:

Modify the external DNS SRV records for your enterprise to point to a Lync Server 2010 Access Edge Server that has its next hop as a Lync Server 2010 Director or a Lync Server 2010 pool. The desk phone will still need to be provisioned internally within the enterprise before using it from outside.

 

Alternatively, users can connect the desk phone to a computer using a USB cable. Make sure that Lync 2010 is running on the computer. Then users can sign in with their Windows credentials by using the pop-up box in Lync 2010.

Lync Phone Edition for Polycom CX700 Continuously Reboots When Using Power over Ethernet (PoE)

Issue:

The Phone Edition for Polycom CX700 may get stuck in a continuous reboot cycle when you use Power over Ethernet (PoE). 

Note: Lync Phone Edition for Polycom CX700 supports PoE and Link Layer Discovery Protocol-Media Endpoint Discovery (LLDP-MED). To make use of this technology, the customer site must have switches that support PoE 802.3AF (PoE Standard) and LLDP-MED 802.1AB.

Resolution:

Use the power adaptor that is shipped with the device, instead of PoE, to power the device.

Note to IT administrator: Please send the Lync team the name of the switch that doesn't work.

Serial number of Lync Phone Edition for Polycom CX600 Is Incorrect in the User Interface

Issue:

The serial number that appears on the screen of the Phone Edition for Polycom CX600 when you select System Information is incorrect.

Resolution: The correct serial number appears on the label on the back of the phone.

Lync Phone Edition for Polycom CX600 Crashes and Reboots When Using Power over Ethernet (PoE)

Issue:

The Phone Edition for Polycom CX600 may crash and then reboot when transitioning from the system idle state to an active state when you use Power over Ethernet (PoE).

Note: Lync Phone Edition for Polycom CX600 supports PoE and Link Layer Discovery Protocol-Media Endpoint Discovery (LLDP-MED). To make use of this technology, the customer site must have switches that support PoE 802.3AF (PoE Standard) and LLDP-MED 802.1AB.

Resolution:

Use the power adaptor that is shipped with the device, instead of PoE, to power the device.

Note to IT administrator: Please send the Lync team the name of the switch that doesn't work.

Buzzing Sound When Using GN1200 Adapter and GN2000 Headset

Issue: An intermittent buzzing sound is heard on the transmit and receive paths when using the Netcom GN1200 adapter plus the GN2000 headset with the Aastra 6725ip phone when the phone is being powered by the wall power adapter.

Resolution:

To resolve the buzzing sound on the headset, install Cumulative Update 1 (CU1). When CU1 is installed, the buzzing sound heard by the other party during transmission is reduced, but may still be present in some cases. To resolve the transmission buzzing, switch to Power Over Ethernet (PoE) and remove the wall power adapter from the phone. You can also use the Plantronics HW251N and HW261N headsets to avoid this problem.

Out-of-Box Audio Devices Require User Authentication for UCUpdates-R2

Issue:

Microsoft Lync 2010 Phone Edition can download updates without authentication, using the hard-coded DNS query of UCDevices-R2. However, you must use one of the public trusted certificates that are preinstalled on the device for image update and log upload to work.

This scenario only applies to device out-of-the-box, first-run behavior, without any prior user sign-in. Once a user has successfully signed in to the device, image update and log upload will function without the public trusted certificate.

Resolution:

In an environment where a private Enterprise root certificate is used, a device can download the root certificate with the following workaround:

A device requires an initial authentication to trigger the bootstrapper to download the root certificate. It does not matter whether the authentication passes or fails.

Once the root certification is in place, the image update and log upload for UCUpdates-R2 will work without user authentication.

For Text Telephony (TTY), Place the Handset on the TTY Device

Issue: To enable Text Telephone (TTY), the instructions on the Settings screen currently tell the user to plug the telephone typewriter device into the headset port. This is incorrect, and the device will not function correctly if this is done.

Resolution: Place the handset on the TTY device, as per instructions provided for the TTY device.

Contacts

Duplicate Contacts Appear in Your Outlook Contacts Folder for Lync Phone-Only Contacts

Issue:

If the phone number normalization rules change on the Lync Server and Exchange contact synchronization is enabled (via the EnableExchangeContactSync in-band setting or user option), Lync creates duplicate Outlook contacts for phone-only contacts that currently appear in your Lync Contacts list.

Resolution:

Remove each phone-only contact from your Lync Contacts list, and then re-add it.

Conferencing

SIP Change of Meeting Organizer Invalidates Current Online Meetings

Issue:

If the Session Initiation Protocol (SIP) of the person who organized an online meetings changes, joining or changing the meeting will no longer be possible.

Resolution: This is not supported. There is no workaround.

Activity Feeds

Note History in Activity Feed Is Not Available for Federated Contacts

Issue:

The Activity Feeds feature works for federated contacts except for Note History. Normally you see the last N notes someone entered in the Activity Feed, but if they are a federated contact you only see their most recent note (in addition to any OOF note, title change, photo change, and office location change).

Resolution: There currently is no workaround for this issue.
