Software Interoperability with Cisco Unified Client Services Framework
Before you deploy Cisco UC Integration for Microsoft Lync to the computers of your users, ensure that there are no other applications installed on the computers of your users that use Cisco Unified Client Services Framework. The following applications use Cisco Unified Client Services Framework:
•
•
Software Interoperability with Click to Call
If you plan to install click-to-call features with Cisco UC Integration for Microsoft Lync, ensure that your client computers do not have the standalone version of Cisco Click to Call installed. These two products are not interoperable.
Software Interoperability with Cisco Jabber
Cisco Jabber and Cisco UC Integration for Microsoft Lync cannot be installed and run on the same client computer. Installation of Cisco Jabber may prevent Cisco UC Integration for Microsoft Lync from being able to successfully sign in. Refer to caveat CSCty89028 in Open Caveats for additional information.
Codecs for Use with Cisco UC Integration for Microsoft Lync
A codec is an implementation of an algorithm capable of performing encoding and decoding on a digital data stream. Codecs are used to encode and decode data, such as sound and video streams, that would otherwise use large amounts of network bandwidth when transmitted or disk space when stored.

Correct Hardware Specification Not Detected on Windows XP SP2
Table 6 states that the minimum service pack requirement for Cisco UC Integration for Microsoft Lync on Windows XP is SP3. We recommend that you do not install Cisco UC Integration for Microsoft Lync on Windows XP with SP2. If you do install Cisco UC Integration for Microsoft Lync on Windows XP with SP2, you must install the latest patches for the operating system.
Cisco UC Integration for Microsoft Lync on Windows XP with SP2 cannot detect the correct hardware specification of the computer. This causes the application to attempt to render video at a resolution that the computer is not capable of. This in turn causes high CPU usage which significantly impairs the responsiveness of the computer.

About Audio and Video Quality
This application is designed to provide premium voice quality under a variety of conditions; however, in some instances users may notice interruptions of audio transmission or temporary audio distortions ("Artifacts") which are considered a normal part of the operation of the application.
These artifacts should be infrequent and temporary when using the application:
•
•
We take reasonable measures to interface with the operating system in ways that decrease the likelihood that other applications running on the system will interfere with the software phone audio and video quality. However, the shared nature of system environments in which these products run is very different than a closed environment like Cisco Unified IP Phones and we cannot guarantee equivalent performance.
The following are some conditions that may cause artifacts:
•
•
•
•
•
•
Avoiding or recovering from the conditions previously listed will help minimize audio distortion artifacts.

Cisco Unified Communications Manager, Business Edition 3000
Release 8.5(6) introduces support for Cisco Unified Communications Manager, Business Edition 3000 Release 8.6(3) and later. Versions prior to this are not supported.

DSCP Packet Marking
Differentiated Services Code Point (DSCP) is an IP field responsible for classification of IP packets. It allows for Quality of Service on IP networks where packet priority is dependent on the DSCP value. Packets with higher DSCP values are given a higher priority as they traverse the network.
Applications running on Windows XP have the ability to set DSCP values without interference from the operating system. Windows Vista and 7 take away this ability. These operating systems reset all DSCP values to zero that have been set by the application if the user is not an administrator and the UAC user account control setting is turned on. This was the behavior on Cisco UC Integration for Microsoft Lync releases prior to 8.5(5). In summary, whereas the DSCP packet markings are application driven on Windows XP, they are operating system driven for Windows Vista and 7 in the non-Administrative user / UAC case.
Cisco UC Integration for Microsoft Lync 8.5(5) includes changes to ensure that audio and video streams are always set up within separate, specific port ranges. This is necessary because the Windows Vista and 7 operating systems need to mark DSCP values for audio and video packets differently and thus need a way to discover how to separately identify audio and video streams. Since the Cisco UC Integration for Microsoft Lync 8.5(5) changes guarantee that audio will always be set up within one port range and video in another, an OS Group Policy can be configured to distinguish one from the other and mark the media packets appropriately.
Perform the following procedure to create audio and video group policies:
Procedure
Step 1
Step 2
Step 3
The port range between these two numbers is the port range all media streams use. From that port range you need two port ranges; an audio port range and a video port range. Calculate these ranges by allocating the bottom half of the range to audio and the top half to video.

Preferred Audio and Video Device Selection
Note
Cisco UC Integration for Microsoft Lync Release 8.5(5) adds capabilities for the selection of preferred audio and video devices.
When Cisco UC Integration for Microsoft Lync is first installed, the devices selected as defaults by the operating system become the currently selected devices. If the user has a preferred audio or video device they wish to use when it is available, they will select it on the Audio or Video tab of the Options window and click Apply after selection is complete. Once applied, the chosen devices will override any other plugged in devices.
If the preferred device is removed from the workstation, Cisco UC Integration for Microsoft Lync will revert to using the operating system default devices. If the preferred device is removed from the workstation and a new device of the same type (audio or video) is introduced, this new device will become the currently selected device. If an additional device is introduced to the workstation while the preferred device is still present, it must be explicitly selected to become the new preferred device.
Forced Authorization Codes
Forced Authorization Codes (FAC) allow for the limiting of phone usage to certain numbers by requiring users to enter authorization codes. When the user calls a number associated with an FAC route pattern, they will be prompted to enter the associated code. If the code is correct the call is allowed to proceed.
Client Matter Codes
Client matter codes (CMC) allow you to manage call access and accounting. CMC assists with call accounting and billing for billable clients by forcing the user to enter a code to specify that the call relates to a specific client matter. You can assign client matter codes to customers, students, or other populations for call accounting and billing purposes.
Suppressing Error Codes
Cisco UC Integration for Microsoft Lync has the ability to suppress error codes. These error codes may be displayed erroneously due to installation or configuration particulars that do not represent actual error conditions.
This suppression is accomplished by creating the following registry keys in HKEY_CURRENT_USER\Software\Policies\Cisco Systems, Inc.\Unified Communications\CUCIMOC:
•
•
–
–
–
–
–
–
–
–
–
–
Account Lockout Prevention
Cisco UC Integration for Microsoft Lync has measures to prevent user account lockup when passwords have been changed during a user session. These measures are triggered when the registry setting EnableActiveDirectoryLockoutPolicy contains the value 1. This value is located in the registry at HKEY_CURRENT_USER\Software\Policies\Cisco Systems, Inc.\Unified Communications\CUCIMOC. It is a String value.
When this registry value is set and a password change occurs during a user session, a popup window is displayed to the user the next time credentials are required. The popup informs the user their current credentials are invalid and prompts them for a valid user name and password. Invalid credentials are deleted from the application and cannot be retrieved.
Cisco Unified Communications Manager 6.1(3) and Conference Participant Lists
If you use Cisco Unified Communications Manager 6.1(3), in conference calls the names of the participants are incorrect in the participant list.
Upgrading from Microsoft Windows XP SP2 to SP3
If you have Cisco UC Integration for Microsoft Lync installed on Microsoft Windows XP with SP2, and you plan to upgrade to SP3, you must first uninstall the following applications from the system:
•
•
After you upgrade the computer to Microsoft Windows XP with SP3, reinstall both applications.
Searching for Contacts That Do Not Have Unique Information
If you have Microsoft Outlook installed and you use the Microsoft Lync or Microsoft Office Communicator window to search for contacts, Microsoft Lync or Microsoft Office Communicator searches your Microsoft Outlook contacts.
If you try to place a call to a matched contact, and the contact does not have a unique email address, SIP address, or name, a dialog box displays all of the contacts in your corporate directory that match the criteria you searched for. Select the contact you require, then select Call.
Other Party Hears Cuts or Clips in Audio on a Call
When you are on a call with audio, or with audio and video, the other party might hear cuts or clips in your audio. The following table shows a possible solution to this problem. This solution relates only to particular audio devices, so you might not see the microphone boost setting referred to in the solution.
Users Hear Echo on Calls
When you are on a call with audio, or with audio and video, you might hear an echo. Camera microphones often have issues with echo. If you have selected your camera microphone as your microphone device, consider using a non-camera microphone as your microphone device.
For information about how to select another microphone device, see the online help, or the Frequently Asked Questions: Cisco UC Integration for Microsoft Lync:
http://www.cisco.com/en/US/products/ps11390/products_user_guide_list.html
Voice Messages Show a Duration of Zero
When you view your voice messages, the duration of some messages might appear as zero. This problem occurs in releases of Cisco Unity and Cisco Unity Connection that are not supported by Cisco UC Integration for Microsoft Lync. To resolve this issue, upgrade your release of Cisco Unity or Cisco Unity Connection to a release that is supported by Cisco UC Integration for Microsoft Lync. For information on supported releases of Cisco Unity and Cisco Unity Connection, see Server Requirements.
Adding an Audio Call to a Video Call Results in an Audio Call
When you add an audio call to a video call, the party on the audio call does not receive a request to add video to their call. When the calls are merged, the call becomes an audio call.
Users of Cisco Unified IP Phone 8900 and 9900 Series Models Cannot Control Desk Phone
If users who have a Cisco Unified IP Phone 8900 or 9900 series model cannot use their desk phone from Cisco UC Integration for Microsoft Lync, you must add the users to the Standard CTI Allow Control of Phones supporting Connected Xfer and conf user group. For more information about how to do this, see the Installation Guide for Cisco UC Integration for Microsoft Lync:
http://www.cisco.com/en/US/products/ps11390/prod_installation_guides_list.html
JTAPI Error When a Call Is Placed
Users might see a JTAPI error about 15 seconds after they place a call, when Cisco UC Integration for Microsoft Lync is set to use the desk phone for phone calls.
To resolve this issue, ensure that your dial plan is set up correctly on Cisco Unified Communications Manager. In particular, ensure that Cisco Unified Communications Manager does not need to wait for more digits to be dialed.
For detailed information on setting up your dial plan, see the Cisco Unified Communications Manager Administration online help, or the Cisco Unified Communications Manager Administration Guide and the Cisco Unified Communications Manager System Guide:
http://www.cisco.com/en/US/products/sw/voicesw/ps556/prod_maintenance_guides_list.html
Opening and Closing Conversation History Window Repeatedly Causes Large Memory Usage
On some computers, if you open and close the conversation history window repeatedly, the cucimoc.exe process might use a large amount of memory. To resolve this issue, you must install the following hotfix:
http://code.msdn.microsoft.com/KB981107/
Limitation with Shared Lines When Deploying with Cisco Unified SRST
If you have Cisco Unified Survivable Remote Site Telephony (SRST) set up in your Cisco Unified Communication system, you can continue to place and receive calls during a system failure. In these circumstances, the Cisco UC Integration for Microsoft Lync uses shared lines to enable you to continue to place and receive calls.
Cisco Unified SRST does not support shared lines with SIP phones. Cisco UC Integration for Microsoft Lync receives only alternate calls if both of the following conditions occur:
•
•
However, the desk phone receives all calls.
Application Might Not Start in Some Circumstances Due to Office Communicator Automation API Error
After you install Cisco UC Integration for Microsoft Lync, then start Microsoft Lync or Microsoft Office Communicator, your Windows operating system might display a message that says "Cisco.Uc.Clients.Moc.UCClient has stopped working." Cisco UC Integration for Microsoft Lync does not start.
This issue can occur when Cisco UC Integration for Microsoft Lync cannot connect to the Office Communicator Automation API. For example, this issue can occur in the following circumstances:
•
•
To fix this issue, perform a repair of Microsoft Lync or Microsoft Office Communicator, as shown in the following steps. Alternatively, reinstall Microsoft Lync or Microsoft Office Communicator.
Procedure
Step 1
Step 2
Step 3
Step 4
Specifying Audio Value Names
Before you install Cisco UC Integration for Microsoft Lync, you must perform some configuration on the computers of your users. You can specify the Cisco Unified Client Services Framework client settings, including an Audio_ISAC_Advertised setting. This specifies whether to enable the advertising of the availability of the iSAC audio codec. Enter one of the following values for this setting:
•
•

How Cisco UC Integration for Microsoft Lync Determines the Audio Codec to Use on a Call
Cisco UC Integration for Microsoft Lync uses Cisco Unified Communications Manager devices for your Cisco UC Integration for Microsoft Lync software, and for your desk phone.
The audio bit rate capability of these devices is one of several factors that determine the audio capability of Cisco UC Integration for Microsoft Lync for the user. You specify this bit rate capability in Cisco Unified Communications Manager.
To configure the bit rate capability of these devices, use the region settings of the device pool that the devices are in. The following settings affect the audio bit rate capability of the devices:
8.0 or later
Max Audio Bit Rate
Earlier than 8.0
Audio Codec
For more information about region and device pool configuration in Cisco Unified Communications Manager, see the Cisco Unified Communications Manager Administration online help, or the Cisco Unified Communications Manager Administration Guide:
http://www.cisco.com/en/US/products/sw/voicesw/ps556/prod_maintenance_guides_list.html
When you place a call in Cisco UC Integration for Microsoft Lync, both endpoints advertise their audio codec capability to the Cisco Unified Communications Manager. The Cisco Unified Communications Manager selects the highest possible common codec between them. The default audio codec is G.711.
Updating the Voicemail Server Value Name
If you migrate from one voicemail system to another, or if the IP address or hostname of your voicemail server changes, you must also update the value of the voicemail server registry key value names.
If you do not update the value of the voicemail server registry key value names, users might still be able to access voice messages from the old voicemail system from the visual voicemail interface in Cisco UC Integration for Microsoft Lync.
For more information about voicemail server registry key value names, see the Installation Guide for Cisco UC Integration for Microsoft Lync:
http://www.cisco.com/en/US/products/ps11390/prod_installation_guides_list.html

Factors That Affect the Video Capability of Users
Factors that affect the frame format and frame rate that can be achieved on a video call are:
•
•
•
•
•
•
•
Determining the Bit Rate Required for a Particular Video Capability
Use Table 11 to determine the minimum bit rate that your Cisco UC Integration for Microsoft Lync requires to attain a particular frame format and frame rate.
Example
To configure Cisco UC Integration for Microsoft Lync for a user to be capable of video with VGA frame size, at 30 frames per second, Cisco UC Integration for Microsoft Lync requires a combined audio and video bit rate of at least 768 kb/s. Allow 64 kb/s for the audio codec to use with VGA frame format.
Configuring the Bit Rate Capability for Cisco UC Integration for Microsoft Lync
Cisco UC Integration for Microsoft Lync uses Cisco Unified Communications Manager devices for your Cisco UC Integration for Microsoft Lync software.
The bit rate, or bandwidth, capability of these devices is one of several factors that determine the video capability of Cisco UC Integration for Microsoft Lync for the user. You specify this bit rate capability in Cisco Unified Communications Manager.
To configure the bit rate capability of the devices, use the region settings of the device pool that the devices are in. The following settings affect the bit rate capability of the devices:
8.0 or later
•
•
Earlier than 8.0
•
•
For more information about region and device pool configuration in Cisco Unified Communications Manager, see the Cisco Unified Communications Manager Administration online help, or the Cisco Unified Communications Manager Administration Guide:
http://www.cisco.com/en/US/products/sw/voicesw/ps556/prod_maintenance_guides_list.html
Example
If you want your devices to be capable of 720p HD video calls at 30 frames per second (fps), configure the Region Settings to allocate a bit rate that can handle the 720p HD video at 30 fps, as well as the audio for the call.
If Cisco UC Integration for Microsoft Lync requires a minimum bit rate of 2000 kb/s to make a HD video call, and the audio bit rate for the region is set to 64 kb/s (G.722, G.711), then you must put the devices in a device pool that is in a region that is configured to have a video call bit rate as shown in the following table:
How Cisco Unified Client Services Framework Determines the Video Capability of Your Computer
Cisco Unified Client Services Framework derives the hardware profile of the machine as a WEI score. Cisco Unified Client Services Framework uses the WEI processor subscore to determine the send and receive video profile that is appropriate for your computer.
Table 12 lists the H.264/AVC levels that are supported, the bit rate and frame format for each level, and the minimum WEI processor subscore that is required to support each level
Limiting of Usage of Bandwidth by Users
The Video category in the Cisco UC Options dialog box contains a slider that enables you to limit the bandwidth that Cisco UC Integration for Microsoft Lync uses for video calls. Table 13 lists the bandwidth settings that are available on the slider, from highest to lowest, and the video implications for each level.

Users Might See Lower Video Quality When Computer Is Connected to Some Models of Cisco Unified IP Phone
Problem
This problem occurs if the link speeds and duplex configuration on either end of the connection are not the same. For example, if the link speed of the port at the PC port is 1000 Mb/s and the switch port is connected at 100 Mb/s. Alternatively, if the link on one end of the connection is half duplex, and the link on the end is full duplex.

Camera Troubleshooting Tips

Some Web Cameras Start When Users Sign In
The correct behavior of web cameras is that web cameras start when users start a video call, or a video conference call. In particular circumstances, some web cameras start when users sign in to Cisco UC Integration for Microsoft Lync. This occurs on particular hardware configurations, with particular web camera driver software.
In these circumstances, Cisco UC Integration for Microsoft Lync controls the web camera. This means that you cannot see a preview of your video in the Set Up Audio and Video dialog box in Microsoft Office Communicator. However, you can still use the web camera for video calls, video conference calls, and so on.
To resolve this problem, install the latest drivers from the manufacturer of your web camera. If your computer is a Lenovo ThinkPad W500, install the drivers at the following URL:
