Initial announcements are always simulcast to each new caller. Periodic announcements are multicast to queued callers at the specified time interval. Callers who join the queue after the periodic announcement begins to play may only hear a portion of the announcement.
CSCuh39611 Disable empty TLS fragments
To support TLS encryption between IM and Presence Service and Microsoft Lync/OCS/LCS, you must modify the Peer Authentication TLS Context configuration on IM and Presence Service using the Cisco Unified CM IM and Presence Administration GUI. Ensure that you disable empty TLS fragments when you modify the Peer Authentication TLS Context on IM and Presence Service before integrating with Microsoft Lync/OCS/LCS for Partitioned Intradomain Federation.
CSCub12922 Adding a new subscriber causes device reset
After you install a new node in an existing cluster, all phones that are registered to the cluster are reset.
CSCue04792 EMCC logout limitation
In the visiting cluster, the current Phone Configuration window has a Log Out button for intracluster Extension Mobility (EM). This button is also used by the visiting cluster administrator to log out an Extension Mobility Cross Cluster (EMCC) phone. Because the EMCC phone is not currently registered with the visiting Cisco Unified Communications Manager, this operation is equivalent to a database cleanup in the visiting cluster. The EMCC phone will remain registered with the home Cisco Unified Communications Manager until it comes back to the visiting cluster due to a reset or a logout from the home cluster by other means.
CSCue08776 Call Queuing interaction with Hunt Groups and Hunt Pilots
The logoff notification functionality for hunt groups changes when Call Queuing is enabled for a hunt pilot. The Hunt Group Logoff Notification does not play when a user logs out of a hunt group, or is logged off because they missed their turn in the queue, if Call Queuing is enabled for a hunt pilot.

CSCtw47643 Cannot Install Signed Microsoft CA Server-Client Authentication Certificate on Microsoft OCS 2008
You cannot install a server-client authentication certificate that is signed by a Microsoft certificate authority (CA) into the local computer store of a Microsoft Office Communications Server (OCS) running Windows 2008. Attempting to copy the certificate from the current user store to the local computer store fails with the error message that the private key is missing.
To resolve this issue, perform the following procedure:
Log on to the OCS as a local user.
Create the certificate.
Approve the certificate from the CA server.
While logged on to the OCS, export the certificate to a file and ensure that the private key is exported.
Log off the OCS (Local Computer).
Log on to the OCS again, but this time log on to the OCS domain as a domain user.
Use the Certificate Wizard to import the certificate file. The certificate is installed in the local computer store. You can now select the certificate in the OCS certificate tab.
CSCts65285 Presence data loss after upgrade from Cisco Business Edition 5000 to Cisco Unified Communications Manager
There is no upgrade path in VMware to upgrade from Cisco Business Edition 5000 to Cisco Unified Communications Manager. A fresh installation is needed. After you perform the fresh installation, IM and Presence Service resynchronizes data with the new Cisco Unified Communications Manager. The Syncagent uses the primary key (pkid) as a comparison field for the synchronization. When the Cisco Unified Communications Manager is reinstalled, all the pkids on Cisco Unified Communications Manager are changed. As such, any existing data on IM and Presence Service is cleaned up and the Syncagent deletes the old data.
Be sure to back up your data before performing this procedure.
CSCto77824 Presence user experiences issues obtaining availability
After an IM and Presence Service server upgrade, when all activated feature services and network services are started, a user experiences inconsistent presence availability. The user can log in to IM and Presence Service but will experience issues obtaining availability information, mainly from SIP-based clients.
This issue is caused when users are provisioned while IM and Presence Service is being upgraded. You must unassign and then reassign the user.
CSCud59343 Access control group permissions interactions
Users can belong to multiple access control groups. When adding a new access control group to existing users, an unexpected reduction in the current level of privileges for some preexisting access control groups may be experienced if the new access control group has the "Effective Access Privileges for Overlapping User Groups and Roles" Enterprise parameter set to Minimum.
Access privilege reduction can occur inadvertently, for example, during an upgrade of Cisco Unified Communications Manager Administration. If the upgrade version supports the Standard RealTimeAndTrace Collection user group, which has the "Effective Access Privileges for Overlapping User Groups and Roles" Enterprise parameter set to Minimum, all users are automatically added to that user group during the upgrade. To resolve the permissions issue in this example, you can remove users from the Standard RealTimeAndTrace Collection user group.
CSCtu18692 CallProcessingNodeCpuPegging alerts for VMware installations
Cisco Unified Communications Manager VMware installations can experience high CPU usage spikes while performing tasks such as DRF backups and Bulk Administration Tool exports. The processes that are commonly responsible for CPU usage spikes are gzip and DRFLocal.
If your system is generating CallProcessingNodeCpuPegging alarms, add an additional vCPU for the support of 7500 Cisco Unified Communications Manager users following the Open Virtualization Archives (OVA) template specifications for your system.
The CallProcessingNodeCpuPegging alert is generated during CPU usage spikes. Other alarms that may also be issued during these CPU usage spikes include CoreDumpFound, CriticalServiceDown, SDLLinkOutOfService, and NumberOfRegisteredPhonesDropped alarms.
When a phone requests a common file from a central or proxy TFTP server and that file has a common name such as ringlist.xml.sgn or is a locale file, the TFTP server sends its own local copy of the file instead of the file from the home cluster of the phone. The phone rejects the file due to a signature verification failure because the file has the signature of the TFTP server's local cluster, which does not match the Initial Trust List (ITL) of the phone. To resolve this issue, you can either disable Security By Default (SBD) for the phone or perform the bulk certificate export procedure to make the Trust Verification System (TVS) return a success when the phone verifies a signature from a different cluster. See the procedure in the "Default Security Setup" section of the Cisco Unified Communications Manager Security Guide for performing a bulk certificate export when migrating IP phones between clusters. To disable Security by Default, see the procedure to update the ITL file for IP Phones in the Cisco Unified Communications Manager Security Guide.
CSCud03278 Empty Far-End When Recording Call Park for some phones
In the current Call Park implementation, the far-end or X-Refci may be empty when recording Call Park for phone models such as 997X, 995X and 896X.
CSCud25228 Limitation for Mobility Voice Mail Avoidance
A possible limitation involves both Voice Mail Avoidance (VMA) and Call Forward No Answer (CFNA) interaction. The scenario is as follows:
CFNA Timer = 12 seconds
Delay Before Ring Timer = 4 seconds
Call Screening Timer = 4 seconds
User Control Confirmed Answer Indication Timer = 10 seconds
00:00 Phone A calls a 3G-registered dual-mode device configured with user control voicemail avoidance, dual-mode B (DM B). This dual-mode has a shared line, Phone C.
00:00 Phone A hears a ringback tone. The CFNA and Delay Before Ring timers start. Phone C rings.
00:04 The Delay Before Ring timer pops. The mobility layer attempts to establish the 3G data channel before extending the call over the PSTN network. The SIP Progress timer (Call Screening timer) starts.
00:08 The Call Screening timer pops. Due to 3G network errors or delays, the mobility layer never received a SIP Progress from the dual-mode mobile client. To make up for this, the CFNA timer is restarted. The call to the mobile identity of DM B is extended over the PSTN network.
00:18 User answers the call on the mobile identity of DM B. The CFNA timer is restarted again. The user does not hear the prompt to "press any digit to be connected."
00:28 The User Control Confirmed Answer Indication Timer fires. Mobility tears down the call and sends a CcRejInd. However, LineCdpc holds onto this CcRejInd because it has not heard from all other shared lines, including Phone C.
00:30 The CFNA timer fires and Phone A is redirected to the voicemail/CFNA destination of DM B/Phone C.
Though unlikely, this scenario is possible. Cisco determined that it is preferable for users to have a lengthened CFNA timer than to have users pick up the call on their mobile identity with, for example, 2 seconds left on the CFNA timer. If the CFNA timer is not restarted and the user does not press a digit within 2 seconds, the call will suddenly be redirected to the CFNA destination, leaving the called user confused.
CSCuc63312 Upgrade to 9.1(1) fails with insufficient disk space
When upgrading Cisco Unified Communications Manager to Version 9.1(1), the upgrade may fail due to insufficient disk space. You will see the following error message:
There is not enough disk space in the common partition to perform the upgrade. For steps to resolve this condition please refer to the Cisco Unified Communications Manager 9.1(1) Release Notes or view defect CSCuc63312 in Bug Toolkit on cisco.com.
Follow this procedure to reduce disk space utilization during an upgrade.
Reduce the amount of traces on the system by lowering the low and high watermarks in the Cisco Log Partition Monitoring Tool. The low watermark adjusts by changing the properties of the LogPartitionLowWaterMarkExceeded alert. The high watermark adjusts by changing the properties of the LogPartitionHighWaterMarkExceeded alert. For more information about the Cisco Log Partition Monitoring Tool, see the Cisco Unified Real-Time Monitoring Tool Administration Guide.
After the upgrade, you must restore the high and low watermarks to their original values in order to avoid premature purging of traces. The default value for the high watermark is 85. The default value for the low watermark is 80.
If you still get the error message, install the COP file named ciscocm.free_common_space_v1.0.cop.sgn that you can find on Cisco.com at Cisco Unified Communications Manager Version 9.1 > Unified Communications Manager/ CallManager/ Cisco Unity Connection Utilities > COP-Files.
This COP file frees disk space to allow the upgrade to proceed.
You must perform an upgrade after applying the COP file.
You will not be able to switch to the previous version after the COP file is installed. For example, if you are upgrading from Cisco Unified Communications Manager 9.0(1) to Cisco Unified Communications Manager 9.1(1) and the previous version is Cisco Unified Communications Manager 8.6, the COP file clears the space by removing the 8.6 version data that resides in the common partition. So after you apply the COP file, you will not be able to switch to the 8.6 version.
If you are unable to perform the upgrade and continue to receive the error message after applying this COP file, the amount of data present on the running version does not leave adequate space for expanding and executing the upgrade. In this case, you can recover more space by removing unused device firmware from the TFTP path. In some cases, having sufficient space for an upgrade will require that you take a backup, reinstall to a larger capacity disk or larger sized Open Virtual Appliance (OVA), and restore. Contact Cisco Technical Assistance Center (TAC) if you require further assistance.
CSCue09155 Cisco Prime Unified Provisioning Manager Business Edition compatibility
Cisco Unified Communications Manager 9.1(1) is not compatible with Cisco Prime Unified Provisioning Manager Business Edition 9.0(1).
Phone support for URI Dialing Display Preference service parameter
Most Cisco Unified IP Phones do not support the URI Dialing Display Preference service parameter. Regardless of how you configure the service parameter, the phone displays a directory URI, if one is available. To ensure full support of this service parameter, make sure that you install the latest phone builds. This service parameter is fully functional system-wide only after the phone firmware implements the changes.
The default value of URI Dialing Display Preference has been changed from "URI" to "DN."
