Deployment Considerations

The tables in this section list the recommended software and firmware releases based on Cisco Unified Communications Release 6.1(1). Note that not every rebuild is tested as part of Cisco Unified Communications. Therefore, additional regression testing in a customer or Cisco-specific certification lab is recommended before deployment.

When deploying IP Communications in a customer environment, please remember the following:

•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://www.cisco.com/kobayashi/sw-center/sw-ios.shtml

•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 impact your implementation. Open caveats can be viewed through the Bug Toolkit, located at:

http://www.cisco.com/cgi-bin/Support/Bugtool/launch_bugtool.pl

•In system upgrades, deploy the chosen release in a lab environment that uses the same product components as the customer's product components before moving it to a production environment.

Important Notes

This section includes important notes related to the testing of Cisco Unified Communications System Release 6.1(1) for IP telephony and includes the following issues:

•Unexpected Reboots on MCS7825-H2 Servers (CSCsl20970)

•Unity Ports in SIP Integration with Unified Communications Manager (CSCsl46826)

•Cisco Unified Operations Manager Defects

•Cisco 2801 Router Crashes Due to Insufficient Memory (CSCsm27446)

•ASA Firewall Performance (CSCsg26064)

•Bidirectional NAT on FWSM Not Supported for VoIP Calls (CSCsh83414)

•Configuring and Registering SCCP Unified IP Phones Affects Virtual Memory (CSCsh87826)

Unexpected Reboots on MCS7825-H2 Servers (CSCsl20970)

Cisco MC7825-H2 or HP DL320G4 servers running the following Cisco Unified Communications Release 6.1(1) software may reboot unexpectedly:

•Cisco Unified Communications Manager 6.1(1a)

•Cisco Unified Presence 6.0(1)

•Cisco Unified MeetingPlace Express 2.0(2)

•Cisco Emergency Responder 2.0(3)

Servers with this issue will appear to become non-responsive for a period of time. If that period of time exceeds ten minutes, the server will reboot and return to normal operation. During the time of non-responsiveness, the server clock will stop updating and will continue to display the same time for the duration of the hang. The frequency of this system hang may vary from only once in many months to multiple times a week.

A diagnostic and a patch file to address this problem are available:

•ciscocm.hpasm-7.8-verify.cop.sgn—A benign diagnostic file that does not affect any server resources; it simply indicates whether the server qualifies for the second file by verifying that the server is a MCS-7825-H2 and that version 7.6 or 7.7 of the HP Advanced Server Management software is installed. This diagnostic file will not install the fix.

•ciscocm.hpasm-7.8-install.cop.sgn—A patch file that removes the older version of the HP Advanced Server Management software and replaces it with the newer 7.8 HP Advanced Server Management software, which addresses the sporadic system halts and reboots. Even if this event has not already occurred on a given server, Cisco recommends installing the second patch file on affected servers.

---

Note Once installed, the patch cannot be uninstalled.

---

The files are available at the Cisco Unified Communications Manager Utilities Software Downloads page (registered customers only) at:
http://www.cisco.com/cgi-bin/apps/tblbld/tablebuild.pl/callmgr-utilpage?psrtdcat20e2

Additional information on this issue is available at:
http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_field_notice09186a00808854a6.shtml

Unity Ports in SIP Integration with Unified Communications Manager (CSCsl46826)

During normal operation, ports on a Cisco Unity Release 5.0 server integrated with a Unified Communications Manager 6.0(1)/6.1(1a) server through a SIP trunk may become stuck in a busy state and stop answering calls. When this condition occurs, the Port Status display in the web-based Status Monitor page shows that the Unity ports have been busy for long periods of time or shows the following error message if the condition is allowed to persist:

hr=0x80070008 (Not enough storage is available to process this command.\x0D\x0A)

Additionally, the following message will appear in the Application Event log viewer once the busy port threshold is reached (which is 240 minutes by default):

Source: CiscoUnity_Miu

EventID: 584

Port XX has been busy since XXXXXX. The system threshold is XXX minutes, indicating that

this port is currently unavailable and may be unable to handle further calls.

Resetting the ports will not free them for use. To restore the ports, you must restart the Unity server. If the server is not restarted, all ports may eventually become busy and the entire Unity server may stop answering calls.

This condition only occurs on Unity servers integrated with a Unified Communications Manager 6.0(1)/6.1(1a) server through a SIP trunk. To avoid this condition, integrate the Unity server with Unified Communications Manager using SCCP voice ports instead of a SIP trunk.

---

Note Using SIP or SCCP between Unity and Unified Communications Server is completely independent of the protocol (SIP or SCCP) running on phones or gateways in the network.

---

Cisco Unified Operations Manager Defects

During Cisco Unified Communications Release 6.1(1) testing, the following defects were identified in Cisco Unified Operations Manager Release 2.0(2):

•CSCsk36823: Cisco Unified Operations Manager should support RouteListFailed and RouteGroupFailed events sent from Cisco Unified Communications Manager

•CSCsl61793: Cisco Unified Operations Manager unable to poll registered gateways

•CSCsl78085: No alert sent for Cisco Unified Communications Manager CPU spikes that occur for less than five minutes

These defects may be fixed in future service pack releases of Cisco Unified Operations Manager. For more information on each defect and to determine if a fix is contained in a subsequent release, click on the defect ID in the list above to view the defect's details and status in the Bug Toolkit (registered customers only).

Cisco 2801 Router Crashes Due to Insufficient Memory (CSCsm27446)

Cisco 2801 Router crashes while loading c2801-adventerprisek9-mz image of Cisco IOS 12.4(15)T, if the default DRAM size is set to 128 MB. This issue is resolved if the DRAM size is set to a higher value, for example, 192 MB or more as the minimum DRAM to run c2801-adventerprisek9-mz in Cisco IOS Release 12.4T is 192 MB.

ASA Firewall Performance (CSCsg26064)

During a sudden or prolonged burst of certain traffic, a Cisco ASA 5500 Series Adaptive Security Appliance may log error messages indicating no interface buffers available and exhibit lower performance, despite reporting CPU utilization of only 90%. Because the CPU utilization is an average calculation, it does not reflect the heavy load burst that caused the condition.

Bidirectional NAT on FWSM Not Supported for VoIP Calls (CSCsh83414)

On a Cisco Catalyst 6500 Series Switch Firewall Services Module (FWSM), you can configure the inspect ctiqbe command to enable CTIQBE protocol inspection, which supports Network Address Translation (NAT) and Port Address Translation (PAT). However, Firewall Services Modules running Release 3.1(5) do not support bidirectional NAT for VoIP calls.

Configuring and Registering SCCP Unified IP Phones Affects Virtual Memory (CSCsh87826)

Configuring and registering non-secure SCCP Unified IP Phones increases the size of the virtual memory of a Unified Communications Manager subsequent node, which is not part of the phone device pool where the phones are configured and registered.
