Introduction
These release notes describe requirements, restrictions, and caveats for Cisco Unified Personal Communicator Release 8.6. These release notes are updated for every maintenance release but not for patches or hotfixes.
Cisco Unified Personal Communicator uses Cisco Unified Client Services Framework, which provides Cisco telephony services and media services for Cisco Unified Personal Communicator.
Before you install Cisco Unified Personal Communicator, review the list of open caveats. See Open Caveats.
System Requirements
•
Network Requirements
This section describes the network requirements for Cisco Unified Personal Communicator.
•
Voice over IP
You must configure voice over IP (VoIP) on your Cisco routers and gateways. See the applicable configuration guides for the models of routers and gateways in use.
Network Ports Used by Cisco Unified Personal Communicator
Cisco Unified Personal Communicator requires inbound and outbound traffic to occur on particular ports through particular protocols.
The operating system sets ports for all inbound traffic except the Real-Time Transport Protocol (RTP). Cisco Unified Personal Communicator sets the following ports to send and receive RTP traffic:
•
•
Cisco Unified Personal Communicator uses the same ports in a given range to send and receive specific streams.
Table 1 describes the inbound ports used by Cisco Unified Client Services Framework.
Table 1 Ports Used for Inbound Traffic by Cisco Unified Client Services Framework
16384-32766
UDP
Receives Real-Time Transport Protocol (RTP) media streams for audio and video. You configured these ports in Cisco Unified Communications Manager. For more information about device configuration files, see the Cisco Unified Communications Manager System Guide:
http://www.cisco.com/en/US/products/sw/voicesw/ps556/prod_maintenance_guides_list.html
Table 2 describe the outbound ports used by Cisco Unified Client Services Framework.
Table 3 describes the ports used by Cisco Unified Personal Communicator.
Note
Configurations that Use Network Ports
You can use the network port information for these configurations:
•
•
Configuring Network Ports on Client Computers
The Microsoft Windows firewall prompts users to block Cisco Unified Personal Communicator when they run it for the first time. Ensure users select Unblock.
Troubleshooting Tips
If users encounter issues with Cisco Unified Personal Communicator functionality after configuring the Microsoft Windows firewall to allow traffic, do the following:
1.
2.
3.
4.
Routing Access Control Lists
You must configure switching and routing ACLs so that Cisco Unified Personal Communicator can communicate with servers and endpoints that might be connected to the voice VLAN. The voice VLAN is the VLAN that carries voice traffic.
By using ACLs, you can permit Cisco Unified Personal Communicator to connect to each server through the appropriate protocol through which the application communicates with that server.
You can use ACLs to permit Cisco Unified Personal Communicator to connect to each server through the appropriate protocol for that server. For example, you can allow UDP traffic in the port range that Cisco Unified Personal Communicator uses for RTP, and then label it with the appropriate QoS actions.
When Cisco Unified Personal Communicator is in software phone mode, this configuration enables Cisco Unified Personal Communicator to send RTP media to, and receive RTP messages from, other audio and video endpoints across the IP network.
For details about ACLs, how to configure the voice VLAN, and how to configure QoS actions, see the switching and routing documentation for your network products.
Network Address Translation
The Cisco Unified Personal Communicator is not compatible with Network Address Translation (NAT). Cisco Unified Personal Communicator cannot use Simple Traversal of UDP through Network Address Translation (STUN), Traversal using NAT (TURN), or any other NAT-traversal scheme.
To traverse NAT, Cisco Unified Personal Communicator must be behind a virtual private network (VPN) connection.

Note
About Audio and Video Quality
Cisco Unified Personal Communicator is designed to provide premium voice and video quality under a variety of conditions; however, in some instances users may notice interruptions of transmission or temporary distortions ("Artifacts") which are considered a normal part of the applications operation.
These artifacts should be infrequent and temporary when using:
•
•
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 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 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 and video distortion artifacts.

Time Required to Install
If the computer on which you are installing Cisco Unified Personal Communicator does not already have Microsoft .NET installed, the Cisco Unified Personal Communicator installer installs Microsoft .NET. This will result in a longer installation time.
Installing Cisco Systems Network Protocol
When you install Cisco Unified Personal Communicator on Microsoft Windows Vista or Microsoft Windows 7, you might be prompted to install Cisco Systems Network Protocol device software. Install this software.
If you do not install this software, you cannot place video calls if you set your Cisco Unified Personal Communicator to use your desk phone for phone calls.
Installing Cisco Unified Personal Communicator Using MSI
The video components of Cisco Unified Client Services Framework require Microsoft Visual C++ 2005 version 8.0.59193 or later. Microsoft Visual C++ 2005 must be installed before you install Cisco Unified Personal Communicator, if you are using MSI to install.
Microsoft provides a Microsoft Visual C++ 2005 redistributable package, vcredist_x86.exe. You can download this package from the following links:
•
To see the command line options, execute the following command:
vcredist_x86.exe /?
The Microsoft Visual C++ 2008 redistributable package is not compatible with Cisco Unified Client Services Framework: the Microsoft Visual C++ 2005 package is required.
Installing the Microsoft Visual C++ 2005 Redistributable Package
You can use an MSI file to install the Microsoft Visual C++ 2005 redistributable package. Extract the files vcredist.msi and vcredis1.cab from vcredist_x86.exe to a temporary folder. Use the following command line option:
vcredist_x86.exe /C /T:<full-path-to-folder>
Example
vcredist_x86.exe /C /T:C:\VCRedist
Use the extracted files to install Microsoft Visual C++ 2005.
Using Translation Patterns Instead of Application Dialing Rules
Cisco Unified Personal Communicator is easiest to install with Cisco Unified Communications Manager Release 7.0 or later, although you can install it with Cisco Unified Communications Manager Release 6.1(3) or later.
Cisco Unified Communications Manager Release 7.0 and later support +E.164 phone numbers. Cisco recommends that you use +E.164 phone numbers with Cisco Unified Personal Communicator, so that outgoing calls are easier to set up.
If you are using Cisco Unified Communications Manager Release 7.0 or later, Cisco recommends that you use translation patterns to set up outbound calls, rather than application dialing rules. If you use translation patterns, the rules are dynamically applied, and you do not need to restart services.
For detailed information on translation patterns, 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
Removing Cisco Unified Video Advantage
If Cisco Unified Video Advantage is installed on a client computer, you must uninstall it before you can install Cisco Unified Personal Communicator. If you do not uninstall Cisco Unified Video Advantage, you are prompted to do so during the Cisco Unified Personal Communicator installation.

This value should not be present in these locations if Cisco Unified MeetingPlace 8.5(x) is used.
This configuration ensures Cisco Unified MeetingPlace is used as the audio provider.
Default Video for all Audio Calls
Cisco Unified Personal Communicator can now be configured to enable video by default for all audio calls and make it a default setting during the first installation of the application. Set the registry key HKEY_CURRENT_USER\SOFTWARE\Policies\Cisco Systems, Inc.\Unified Communications\CUPC8\VideoCallByDefault or HKEY_CURRENT_USER\SOFTWARE\Cisco Systems, Inc.\Unified Communications\CUPC8\VideoCallByDefault to true to enable this functionality.
If any of the registry keys are in the Policies hive, the key must be in that same hive or it will be ignored.
The value of this registry key will be false if the registry key value field is empty or if some exception occurs. Otherwise, it will be parsed and set to true or false acccording to what the user has set.
DOS Attack on Unity Connection Voicemail Server
Cisco Unified Personal Communicator does not use the Voicemail Web Service when it is connected to Cisco Unity Connection. Cisco Unified Personal Communicator will ping this service every two minutes if it becomes unavailable even though it is not actually used for Cisco Unity Connection connections. This fact, in combination with incorrect Cisco Unified Presence configurations, can have the same effect as a denial of service (DOS) attack on the Cisco Unity Connection server. The Voicemail Web Service should be disabled if Cisco Unity Connection is used.
Disable the Voicemail Web Service using the following procedure:
Step 1
Step 2
Step 3
Step 4
Step 5
Step 6
Note
The next time Cisco Unified Personal Communicator starts, the server health information for the Voicemail Server is missing but information for the Voice Message Store should remain and show a connection.
Cisco Unified Personal Communicator will no longer send requests to the Voicemail Web Service. This change will take effect for users that are part of the changed profiles.
Installer Fix
An installer condition associated with the Microsoft Visual C++ 2005 Redistributable in previous versions of Cisco Unified Personal Communicator prevented the user from installing the client in certain situations. This condition would fail incorrectly when a user had a new version of the package installed. This condition is now fixed to ensure that if either the 8.0.59193 or 8.0.61001 versions of the package are installed, the condition will pass. The condition will fail once again however if any versions newer than this are subsequently installed.
A public installer property can be used to override this condition is necessary. Name the installer property to VCREDISTOVERRIDE and set its value to TRUE. The following is an example of how to override this condition when installing from the command line:
msiexec /i [Product].msi VCREDISTOVERRIDE=TRUE
Desktop Phone Mode Error
Cisco Unified Personal Communicator compares the local JTAPI file against the version hosted on Cisco Unified Communications Manager the first time it enters desktop phone mode each session. It downloads the server version to perform this comparison. If the server version cannot be downloaded within 30 seconds, an error is produced. Users can safely ignore this error and continue entering desktop phone mode.
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.
Microsoft Windows Vista and 7 applications do not have the ability to set DSCP values. 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 Unified Personal Communicator releases prior to 8.5(5). DSCP packet marking is operating system driven for Microsoft Windows Vista and 7 in the non-Administrative user / UAC case.
Cisco Unified Personal Communicator 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 Microsoft 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 Unified Personal Communicator 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.

Automatic Tethered Phone Selection
Cisco Unified Personal Communicator has capabilities for the automatic selection of a tethered phone. Cisco Unified Personal Communicator users will often have multiple desktop phone devices assigned to them but only one that is tethered to their workstation through an Ethernet cable. This new feature ensures that the tethered phone is always selected when a Cisco Unified Personal Communicator user enters desktop phone mode.
This feature is disabled by default. Set the AutomaticTetheredPhoneSelection registry key to true through a group policy setting to enable it. This key is located in HKEY_CURRENT_USER\Software\Policies\Cisco Systems, Inc.\Client Services Framework\AdminData. For additional information on setting group policies and registry settings in Cisco Unified Personal Communicator, see the following chapters in the Deployment Guide for Cisco Unified Presence Release 8.6:
•
•
The following usage scenarios outline the operation of this feature when it is enabled through the registry:
•
•
•
•
Note
Preferred Audio and Video Device Selection
Cisco Unified Personal Communicator has capabilities for the selection of preferred audio and video devices.
When Cisco Unified Personal Communicator 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 Unified Personal Communicator 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.
Automatic Server Discovery
Cisco Unified Personal Communicator contains a feature for the automatic discovery of Cisco Unified Presence servers. Previous versions of Cisco Unified Personal Communicator required either the administrator to push the server address to a client through a registry key or the client to manually enter the server address on the logon screen. Cisco Unified Personal Communicator can now use DNS SRV lookup to automatically find the Cisco Unified Presence server in the client's Active Directory domain.
DNS SRV is a record an administrator adds to a DNS server. This record can be added to any DNS domain but its addition to the Active Directory domain is recommended. A DNS SRV record is unlike a typical DNS record. Instead of storing a simple Host name and IP address pairing, DNS SRV records details about a particular service on a network. A DNS administrator can map many hosts to the same service name and assign a priority and weighting to each. This provides support for load balancing and failover services.
Cisco Unified Personal Communicator uses the following logon process when making use of the DNS SRV feature:
1.
2.
3.
4.
Cisco Unified Personal Communicator continues to support server identification through a registry key pushed to the client or manual entry.
See the section Automatic Server Discovery in Chapter 13 of the Deployment Guide for Cisco Unified Presence Release 8.6 for additional information on configuring this feature. This section is available at the following location:
Dial via Office
Cisco Unified Personal Communicator contains Dial via Office (DVO) functionality. DVO is a feature that allows a user to configure an additional phone number for the purposes of call forwarding. Users who have configured a DVO number are called through their standard office phone number and the call is then forwarded to the additional number specified. Calls placed by the user display the caller ID of their standard office phone number.
Note
DVO is configured on the Call Options window. Click Calls and then select the Dial via Office checkbox. Enter the DVO number in the space provided.
DVO functionality is triggered when the call is answered. This can be through the user answering the call or the call being routed to voicemail.
Note
Enhanced Directory Integration
Enhanced Directory Integration (EDI) was introduced in Cisco Unified Personal Communicator 8.5(2). EDI provides additional capabilities to the basic directory integration already present in Cisco Unified Personal Communicator. EDI simplifies the integration of Cisco Unified Personal Communicator and corporate directory services. This improved integration provides benefits to organizations of any size with different directory architectures and sizes. Advantages of Enhanced Directory Integration include:
•
•
•
•
•
•
Table 11 lists the differences between basic and enhanced integration.
This section contains the following topics:
Configuration
EDI is enabled using either an Active Directory group policy or Microsoft Windows registry settings. Cisco provides group policy template files that include directory configuration settings. These templates are available in ADM and ADMX formats for Microsoft Windows Server 2003 and 2008 environments.
Once enabled, most administrators should not need to provide additional directory integration configuration. Cisco directory integration uses automatic discovery to find the directory service Microsoft Windows uses to discover a domain controller or global catalog server. This discovery is performed with a DNS Service request. This request will search for the domain controller or global catalog server in the native domain of the user's workstation. The native domain can be identified by examining the USERDNSDOMAIN environment variable.
Directory server information can be configured manually if the directory server is not discoverable through a DNS query. Configuration is performed using a group policy or through manipulation of the registry. The administrator should configure the IP address or Host Name of the primary and backup directory server as well as the port requests are received on.
Connections to a global catalog server are recommended. This server contains the primary directory attributes for all users in a Microsoft Windows domain forest. Administrators can connect to a domain controller instead if the required search attributes are not present on the global catalog server. If possible, administrators should enable missing search attributes on the global catalog server so it can be used. Administrators should confirm with directory managers that photo attributes are available on the global catalog server when using contact photographs. If possible, enable these attributes on the global catalog server instead of relying on the domain controller. Directory integration looks for domain controllers on port 389 and global catalog servers on port 3268 by default. Specifying a port during configuration overrides these defaults.
Security
EDI encrypts all authentication data by default. If encryption is required for user credential and query data, SSL can be enabled. In this scenario, the SSL connection certificate must be present in the Microsoft Windows certificate store. In a Microsoft Windows domain, this certificate would typically be part of the workstation certificate store by default. SSL uses port 636 when communicating with a domain controller and port 3269 when communicating with a global catalog server. These defaults can be changed.
Microsoft Windows encryption may need to be disabled in non-Microsoft Windows Server environments. In such instances a basic bind will be used to connect to the directory. Credentials are transmitted in clear text when a basic bind is in use. SSL usage is highly recommended in this scenario.
Administrators can use a common set of credentials for directory integration to authenticate for directory queries. Administrators would push the credentials out to all workstations using a group policy or manipulation of registry settings. This is typically used when third party directory services are used. If credentials are not provided but required for the query, directory integration will attempt an anonymous bind to the service.
Photo Retrieval
Basic directory integration provides for the retrieval for contact photograph Universal Resource Indicators (URI). EDI provides three methods for photo retrieval:
•
EDI retrieves the attribute content of the directory attribute defined by PhotoUri group policy or registry setting. Directory integration then parses the attribute content. If the attribute contains binary data it will be displayed as a JPEG photograph. If the attribute contains a URI the photo will be retrieved from it. If a directory user object stores photos in the "thumbnailphoto" attribute, setting the PhotoURI setting to "thumbnailphoto" forces directory integration to retrieve the photo from this field. A photo can also be stored in the "jpegPhoto" attribute in the active directory.
•
EDI retrieves a contact photo based on the provided resource indicator. This resource indicator is formatted as a static HTTP request. No error checking is provided.
•
EDI retrieves a contact photo based on a dynamically constructed resource indicator using directory attributes. The URI is typically constructed using a base value plus the dynamic portion of the URI drawn from directory attributes.
Forced Authorization Codes Support
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.
TLS and SRTP Support
Cisco Unified Personal Communicator supports TLS for signaling and SRTP for secure media streaming.
Cisco VPN Client and CAST video
The Cisco VPN Client does not support CAST video on computers running in a 64 bit environment. Use the Cisco AnyConnect Client instead of the Cisco VPN Client in 64 bit environments.
Cisco VT Camera II Support on Microsoft Windows 7 64-bit
Cisco Unified Personal Communicator includes support for the Microsoft Windows 7 64-bit and the Cisco VT Camera II. The Cisco VT Camera II however is not supported on Microsoft Windows 7 64-bit. Although Cisco Unified Personal Communicator provides support for both, this does not mean the Cisco VT Camera II will run on Microsoft Windows 7 64-bit using Cisco Unified Personal Communicator. Users of the Cisco VT Camera II running a Microsoft Windows 7 64-bit environment must use a different camera.

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 Unified Personal Communicator. To resolve this issue, upgrade your release of Cisco Unity or Cisco Unity Connection to a release that is supported by Cisco Unified Personal Communicator. 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 8961, 6900 Series, and 9900 Series Models Cannot Control Desk Phone
If users with a Cisco Unified IP Phone 8961, 69xx, or 99xx model desk phone cannot use their desk phone from Cisco Unified Personal Communicator, 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 Deployment Guide for Cisco Unified Presence:
http://www.cisco.com/en/US/products/ps6837/products_installation_and_configuration_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 Unified Personal Communicator 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
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 Unified Personal Communicator 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 Unified Personal Communicator receives only alternate calls if both of the following conditions occur:
•
•
However, the desk phone receives all calls.
Specifying Audio Value Names
Before you install Cisco Unified Personal Communicator, 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 audio iSAC codec. Enter one of the following values for this setting:
•
•
The iSAC audio codec is only supported in Cisco Unified Communications Manager Release 8.0 and later.
How Cisco Unified Personal Communicator Determines the Audio Codec to Use on a Call
Cisco Unified Personal Communicator uses Cisco Unified Communications Manager devices for your Cisco Unified Personal Communicator 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 Unified Personal Communicator 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

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 12 to determine the minimum bit rate that your Cisco Unified Personal Communicator requires to attain a particular frame format and frame rate.
Example
To configure Cisco Unified Personal Communicator for a user to be capable of video with VGA frame size, at 30 frames per second, Cisco Unified Personal Communicator 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 Unified Personal Communicator
Cisco Unified Personal Communicator uses Cisco Unified Communications Manager devices for your Cisco Unified Personal Communicator software, and for your desk phone.
The bit rate, or bandwidth, capability of these devices is one of several factors that determine the video capability of Cisco Unified Personal Communicator 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 Unified Personal Communicator 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 13 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 section in the Cisco Unified Personal Communicator Options dialog box contains a slider that enables you to limit the bandwidth that Cisco Unified Personal Communicator uses for video calls. Table 14 lists the bandwidth settings that are available on the slider, from highest to lowest, and the video implications for each level.

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 Unified Personal Communicator. This occurs on particular hardware configurations, with particular web camera driver software.
In these circumstances, Cisco Unified Personal Communicator controls the web camera. Other applications cannot access the camera. 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:
