Cisco Unified Communications Manager allocates an audio only conference bridge when the initial leg is triggered from an audio capable phone to video capable phones through an Early Offer (EO) or Best Effort Early Offer (BEEO) trunk. This scenario disables video in a conference call, even when video-capable endpoints are connected. To avoid this problem, you must perform the following steps.
Set the Allocate Video Conference Bridge For Audio Only Conferences When The Video Conference Bridge Has Higher Priority service parameter to True.
In the MRGL list, set the video conference bridge with a higher priority than the audio conference bridge.
SIP IPv6 Calls Fail When Using UDP
Cisco Unified Communications Manager does not support SIP IPv6 signaling over UDP where the MTU is greater than 1500. To ensure that calls do not fail, change the transport protocol to TCP.

IM and Presence Service
Availability and IM Broken Between Publisher and Subscriber After
This information applies to CSCuo65513.
After you upgrade
a multinode deployment, users that are assigned to one node cannot see the
availability of users that are assigned to another node, nor can they send
instant messages to users that are assigned to another node.

This documentation update resolves CSCuo56537.
FIPS 140-2 mode for
IM and Presence Service is pending certification at
this time and is not supported until certification is complete.
following information before you enable or disable FIPS 140-2 mode for
IM and Presence Service: After you enable or disable
FIPS 140-2 mode for
IM and Presence Service, the Tomcat certificate is
regenerated and the node reboots. The Intercluster Sync Agent syncs the new
Tomcat certificate across the cluster; this can take up to 30 minutes. Until
the new Tomcat certificate is synced across the cluster, an
IM and Presence Service subscriber node cannot access
information from the
IM and Presence Service database publisher node. For
example, a user who is logged in to the Cisco Unified Serviceability GUI on a
subscriber node cannot view services on the
IM and Presence Service database publisher node. Users

IM and Presence Service Needs to Support Install Against a Small Disk Cisco Unified Communications Manager Publisher
This information applies to CSCuo54588
Cisco Unified Communications Manager IM and Presence Service cannot be deployed when a Cisco Unified Communications Manager 40-GB- or 60-GB-disk OVA deployment size is used.
The IM and Presence Service installer determines whether the publisher node is a valid system. The installer interprets a Cisco Unified Communications Manager OVA deployment size of less than 80 GB (for example, 40 GB or 60 GB) as invalid and does not proceed with the installation.
IM and Presence Server Pings to Jabber Are Not Configurable
IM and Presence server updates the presence status of the user as Unavailable if it does not receive a keep-alive from the client after two 1-minute pings.
The timings for these pings are hard-coded on the server side and are not configurable.

Failure to Add Unified CM Cluster for Collaboration Edge with TLS Verify Enabled If Unified CM Shares Certificate
If a Unified Communications Manager
cluster is deployed using a multiserver Tomcat certificate, you cannot add the cluster
for mobile remote access to a Cisco TelePresence VCS-C/Expressway-C with the
TLS verify mode enabled. To add a cluster to the Cisco TelePresence
VCS-C/Expressway-C with TLS verify enabled, specify the first node
that is mentioned in the Subject Alternative Name (SAN), or change the order of the SAN items
making the Unified Communications Manager the first publisher on the SAN list. However, the issue
still remains for the IM and Presence Service cluster, and this cluster must be added
with TLS verify mode disabled.
can disable TLS verify mode for both the Unified Communications Manager and IM and Presence Service clusters. This issue is resolved
with the release of Cisco TelePresence VCS-C/Expressway-C X8.2.
For details about how
to add a Unified Communications Manager cluster to a Cisco TelePresence VCS, see your Cisco
TelePresence VCS product documentation.
Failover Interoperability with Cisco Jabber Clients
If you have configured redundancy with backup servers, the following interoperability limitations apply to Cisco Jabber clients when the primary Cisco Unified Communications Manager server goes down:
Softphone mode—If the Jabber client is in softphone mode, automatic failover is supported so long as the client has already downloaded the device information from the TFTP server (this occurs upon client startup). When the primary server goes down, the Call Preservation feature is invoked. All active Jabber calls are preserved, but users cannot invoke call-processing features. Once all preserved calls have ended, the Jabber client automatically switches over to the backup server. When the primary Cisco Unified Communications Manager server becomes available again, control reverts to the primary server.
Deskphone mode—If the Jabber client is controlling a deskphone, automatic failover is not supported. However, you can switch over to the backup Cisco Unified Communications Manager server by signing out and signing in again on the Jabber client, or by switching to softphone mode, and then back to deskphone mode again.

Presence Web Service Unable to Send Event Notification if Endpoint Registered with FQDN
This information applies to CSCuo48936.
If a Presence Web Service (PWS) application registers an endpoint using anything other than an IP address, the PWS is unable to send notifications to that endpoint. As a result, applications that were developed using the PWS are unable to receive events from IM and Presence Service nodes. To resolve this issue, you must use an IP address when registering the endpoint.
Route Filter and Associated Route Patterns
When configuring your call routing, make sure that you don't assign a single route filter to too many route patterns. A system core could result if you were to edit a route filter that has hundreds of associated route patterns, due to the extra system processing that is required to update call routing for all of the route patterns that use the route filter. Create duplicate route filters to ensure that this does not occur. For more information see CSCup04938.

RtpLib Callbacks Usage
This information applies to CSCuj63480.
An application can
define a callback function in order to receive information about such things as
operation completions, data transfers, and errors. Callback functions can be
specified when an endpoint is created, when a stream callback is opened, and
when a stream callback operation is initiated. If a callback operation is not
specified, a corresponding stream callback is invoked if defined. If a stream
callback is not specified, a corresponding callback endpoint is invoked if
If you define
the callback function, it is invoked for every operation that is initiated on a
corresponding stream or endpoint. Consideration should be given to the case
where a callback function is defined as a method in an object that is
dynamically created and destroyed. In that case the destruction should not
occur until all initiated operations are complete.
If set to
True, indicates that silence has been detected.
