System Release Notes for IP Telephony: Cisco Unified Communications System Release 9.0(1)
As part of its standard methodology Cisco Systems performs system-wide testing of the Cisco Unified Communications family of products to supplement the product-level testing performed on each Cisco Unified Communications product.
A major deliverable of the System Release and Cisco Unified Communications System testing is a recommendation of compatible software releases that have been verified by the testing teams. The recommendations are not exclusive and are in addition to interoperability recommendations for each of the individual voice application or voice infrastructure products.
For information about component software releases for Cisco Unified Communications System Release 9.0(1), see System requirements. Software compatibility data for all Cisco Unified Communications System releases, as well as updated compatibility information for this release, is available from the Cisco Unified Communications Compatibility Tool at:

The EOS date is the last date to order the product through Cisco point-of-sale mechanisms. The product is no longer for sale. Another process, the end-of-life (EOL) cycle, guides the final business operations associated with the product.
The EOL process consists of a series of technical and business milestones and activities that, when completed, make a product obsolete. After a product becomes obsolete, it is not sold, manufactured, improved, repaired, maintained, or supported.
Tables in this section list the recommended software and firmware releases based on Cisco Unified Communications System Release 9.0(1) for Contact Center. Note that not every rebuild is tested as part of the Cisco Unified Communications System testing. Therefore, additional regression testing in a customer or Cisco-specific certification lab is recommended before deployment.
- At the minimum, customers should deploy the software release recommended in these tables.
- For CSA, customers should use the latest engine and policy release. CSA software is available at: http://www.cisco.com/cgi-bin/tablebuild.pl/csa
- For other software components, customers should use the most current rebuild of a maintenance release. For IOS, information about the latest releases, including deferral advisories, is available at: http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp
- If the recommended release has been deferred to a subsequent release, customers should use the subsequent release.
- Before deploying a release, examine the open caveats in the chosen release to determine if any will affect your implementation. Open caveats can be viewed through the Bug Toolkit, located at: http://tools.cisco.com/Support/BugToolKit/
- Deploy the chosen release in a lab environment that uses the same product components as the customer's product components before moving to a production environment.

Limitations and restrictions
If you are a Cisco partner or a registered Cisco.com user with a Cisco service contract, you can use the Bug Toolkit to find caveats of any severity for any release. Access the Bug Toolkit at: http://tools.cisco.com/Support/BugToolKit/.
Cisco offers a Cisco Notification Service that allows you to set up one or more profiles that enable you to receive email notification of new Field Notices, Product Alerts, or End of Sale information for the products that you select. The Cisco Notification Service is available at: http://www.cisco.com/cisco/support/notifications.html.
DTMF signaling type 'no preference' with DTMF relay sip-kpml
This combination results in bulk call failures during heavy traffic loads, followed by a gateway crash. To recover from the crash the gateway router must be reloaded. For more information, see CSCtq56727, SIP GW crash with MALLOCFAIL during heavy call traffic.
Cisco Unified Contact Center Express compatibility considerations
Unified CCX versions prior to 8.5(1) are not supported with Unified Communications Manager 9.0 or higher. You must upgrade Unified CCX to 8.5(1)SU3 or 9.0(1) before upgrading Unified Communications Manager to 9.0(1) or higher. For more information, see CSCts67056.
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.
Critical caveats are intended to address those defects that can adversely impact operations if customers are not aware of the situations and conditions where specific issues can arise.
Call failure on shared lines after node restart
In very rare instances, restarting a Unified Communications Manager node can cause shared lines not to be able to make or receive calls if the devices sharing the line are registered to different nodes. This situation can occur when one of the nodes is restarted or a series of nodes are restarted.
If this occurs, customer will not be able to make or receive calls on affected lines. In very rare instances, a customer must re-register a phone, or restart the cluster to clear the problem.
For more information, see CSCtz83824.
Call failure during extended end-to-end RSVP traffic
Under extended load with heavy supplementary services, RSVP DSP sessions can hang due to lack of RSVP MTP resources. These hanging sessions can occur from supplementary calls with end-to-end RSVP. Customers with heavy supplementary services on end-to-end RSVP links can experience call failures once the RSVP resources are exhausted.
No issue is seen by callers until the RSVP resources are fully exhausted.
System administrators must reload the RSVP resource to clear the connections.
This defect is resolved and the fix will be available to customers in 15.1(4)M5. This defect fix has also been approved for 15.2(3)T1.
For more information, see CSCtz32912.
The table below lists caveats, grouped by severity, that are resolved now but are not included in the recommended component versions of Cisco Unified Communications System Release 9.0(1) for IP telephony.
For information about the caveats that were resolved in specific versions of each component, see the appropriate release notes for each component.
Table 4 Resolved caveats not included in Cisco Unified Communications Release 9.0(1)
Out of disk space on root partition on a 55GB installation
Hang RSVP-MTP sessions during extended e2eRSVP traffic
CUCM node restart can cause shared lines to not make/receive new calls
Media stream inactive after conf call w/ CME endpoint drops to p2p call
Hang RSVP-MTP sessions during extended e2eRSVP traffic
