Cisco Collaboration Systems Release 12.1-12.0(1)
As part of our standard methodology for each Cisco Collaboration Systems Release, we:
-
Perform system-wide testing of Cisco Collaboration products to supplement the product-level testing performed on each collaboration product.
-
Recommend compatible software releases that were verified by the testing teams. The recommendations are not exclusive and are in addition to interoperability recommendations for each of the individual applications or products.
For software compatibility data, see the Cisco Collaboration Systems Release Compatibility Matrix.
Note
Software compatibility data for all Cisco Collaboration Systems releases before 10.5(1) is available from the Cisco Collaboration Systems Compatibility Tool.

Important Notes
This section includes important notes related to the testing of Cisco Collaboration Systems Release 12.1/12.0(1) and includes the following issues:
DHCPv6 as Default for Dual-stack DX
If you configure a DX with CE build as dual-stack endpoint on Unified CM, you won’t see an IPv6 address on the endpoint. To allow the endpoint to use an IPv6 address, turn on the DHCP IPv6 setting under the endpoint’s network configuration. For more details, see CSCvi49092.
TFTP Server Address Not Automatically Updated
If you try to reconfigure a DX endpoint from IPv6 to IPv4, the TFTP server address does not automatically get updated to IPv4. To work around this issue, you can either do a factory reset of the device, or change the addressing mode on the device to IPv4. For more details, see CSCvi49095.
Unified CM IP Address Not Displayed When Setting Up CE Device
The Unified CM IP address is not displayed when setting up your CE device. You will see the following in the display: A Cisco UCM service at <IP address> is available in your network. However, the phone registration works and you can continue with the phone setup. For more details see, CSCvi49099.
Intermittent CCM Core Dump in SIPHandler for Options Ping Over TLS
Intermittently there are CCM process core dumps in the SIPHandler process while sending the Options Ping over a TLS-enabled SIP trunk. There is currently no workaround. See CSCvc05283 for more details.
Conference Bridge Cannot Register as IPv6 Entry
When Unified CM and IOS gateways are in dual-stack mode, an IOS conference bridge cannot register as an IPv6 entry. Initially the conference bridge registration results in a rejected status. Then, after a few seconds, it automatically registers with Unified CM as an IPv4 entry. The IPv6 entry status shows None. There is no known workaround. See CSCvd42357 for more details.
Unified CM Not Sending SIP Message Session IDs
Unified CM is not including Session IDs for some SIP messages. There is no workaround. For more details, see CSCve66877.
Cisco Prime Collaboration Deployment Running After Upgrade
When running multiple upgrade tasks on Cisco Prime Collaboration Deployment with one cluster having several nodes, it causes Cisco Prime Collaboration Deployment to be stuck in acquiring lock for updating databases.
To fix this issue, restart Cisco Prime Collaboration Deployment Tomcat and either:
-
Resume the tasks and complete the remaining server upgrades.
-
Cancel the tasks and upgrade the remaining servers manually.
For more details, see CSCvf43173.
show dspfarm profile Information Not Displayed
In calls from endpoints that don’t support Keypad Markup Language (KPML), the show dspfarm profile command doesn’t show the actual resources being used. The profile shows only the SCCP connections. For more details, see CSCvd91119.
Caller-ID Not Changed After Transfer
On Cisco Webex Call phones, the caller-ID is not updated properly after a transfer from enterprise phones. For more details, see CSCve56223.
Can't Retrieve Directory Information in Contact Search
In an IM and Presence Service inter-cluster peering deployment when Unified CM and IM and Presence Service are configured with Active Directory, you are unable to search for contacts in a remote cluster. You can successfully find contacts in your local cluster. For more details, see CSCvf27648.
Support for Hostname When Configuring InformaCast Wizard
If you enter the FQDN of the InformaCast server on the Connecting to InformaCast page of the wizard, the install wizard for Emergency Notifications Paging may fail to connect to InformaCast. To work around this potential issue, enter the IP Address instead of the FQDN of the InformaCast.
For more details, see CSCvf58052.
Cisco Expressway or VCS Application Error
Sometimes Cisco Expressway or Cisco VCS reports an application error reporting that an unexpected software error was detected, and the internal application process restarts automatically. For more information, see CSCvc06946.
PVDM2-DM and NM-HDV2 Modules Not Supported
Effective with Cisco IOS Release 15.6(2)T, PVDM2-DM and NM-HDV2 modules are not supported on Cisco 2900 Series Integrated Services Routers. For more information, see Cross-Platform Release Notes for Cisco IOS Release 15.6M&T.
Unified CM Phantom IP Addresses When Discovered by VCS
In a Mobile Remote Access (MRA) environment consisting of MRA endpoints, Unified CM, and VCS, MRA endpoints may not register if stale database entries are present. To work around this issue, you can clear the old IPs. For more information, see CSCuy48059.
High Availability Support for Out-of-Band DTMF Interworking
-
RFC 2833 to out-of-band DTMF Interworking
-
Out-of-band to RFC 2833 DTMF Interworking
-
Out-of-band to out-of-band DTMF
Once failover happens, for DTMF to work, call again.
For more information, see CSCus57502.
Intermittent Calls to Destination Fail Through TLS Trunk
Calls fail intermittently when two TLS trunks are configured with same destination IP and port number. To work around this issue, configure two TLS trunks with same destination IP and different port number. Or configure two TLS trunks with different destination IP but same port number. For more information, see CSCus63305.
Secure SIP Trunk Security Profile Considerations
For a Cisco Extension Mobility Cross Cluster (EMCC) solution, a Secure SIP Trunk profile cannot be configured on the special EMCC SIP Trunk. This means that Transport Layer Security (TLS) will not be used to encrypt signaling for any calls that are initiated by the Home cluster to a Visiting cluster Local Route Group or PSTN gateway. For more information, see CSCtw76154
Show Connection Status Not Updated After Unified Communications Manager Failover for Jabber in Mobile and Remote Access Deployment
When Jabber is registered using Mobile and Remote Access, the "Connection status" window shows connected address as the primary Unified Communications Manager, even after a Unified Communications Manager failover has happened, and the client is registered to the secondary Unified Communications Manager. For more information, see CSCuo89949.
