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.
Empty TLS Fragments
To support TLS
Presence Service and Microsoft Lync/OCS/LCS, you must modify the Peer
Authentication TLS Context configuration on
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
Presence Service before integrating with Microsoft Lync/OCS/LCS for
Partitioned Intradomain Federation.
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.
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.
Queuing Interaction with Hunt Groups and Hunt Pilots

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.
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
Cisco Unified Communications Manager. The Syncagent
uses the primary key (pkid) as a comparison field for the synchronization. When
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.
Presence User Experiences Issues Obtaining Availability
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.
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
Privileges for Overlapping User Groups and Roles" Enterprise parameter set
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
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.
CallProcessingNodeCpuPegging Alerts for VMware Installations
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.
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
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
Setup" section of the
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
Communications Manager Security Guide.

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.

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.
