System Release Notes for
North America IP Telephony:
IP Communications System
Test Release 4.4
This document comprises the release notes for IP Communications (IPC) System Test, Release 4.4. The tested system includes a validated set of the following components: Cisco Unified CallManager, CRS (Unifed Contact Center Express), Cisco Unity (Microsoft Exchange 2000/2003), Cisco MeetingPlace, Cisco Emergency Responder, Cisco Personal Assistant, Cisco Voice Gateways, Cisco Catalyst Voice Gateways, Cisco routers, and Cisco Catalyst switches.
It is standard methodology for Cisco Systems to perform systems-wide testing of IP Communications, supplementing the systems test performed on each IPC product.
A major deliverable of the IPC System Test is a recommendation of compatible software releases verified by the test. Customers that have deployed or are planning to deploy multiple voice application and voice infrastructure products in their network can adopt these recommendations. These recommendations are not exclusive, and are in addition to inter-operability recommendations for each of the individual voice application or voice infrastructure products.
Contact center components have also been tested. For additional information, please refer to the documents at the following URL:

For additional information, refer to the "Troubleshooting and Technical Tips" chapter in the System Test Architecture Reference Manual for North America IP Telephony.
ISDN Memory Leak Issues
There are two or more caveats that were opened resulting from an ISDN memory leak issue (for example, CSCek28604 and CSCse79994). They have been resolved in IOS Release 12.4(10).
T38 Fax Call Disconnected over MGCP 1.0
Symptoms: A gateway-controlled T.38 fax relay between an MGCP gateway and another gateway may be disconnected unexpectedly.
Conditions: This symptom is observed on a Cisco platform that is configured for Voice xGCP.
Workaround: This problem is corrected in IOS Release 12.4(8a).
Considerations when Using IP-to-IP Gateways
When using IP-to-IP gateways, incoming dial peers must be configured to provide codec, Fax, and DTMF selection for incoming calls.
Considerations when Using Call Park and Load Balancing
Load balancing of calls inbound to the Cisco Unified CallManager cluster is done automatically by default because the gatekeeper randomly selects one of the subscribers registered within the zone. When using Call Park, ensure that the range of directory numbers is specified for all the servers in the cluster that are running the Cisco Unified CallManager service.
Limitation on Delivery of Secured Messages between Cisco Unity Subscribers
Cisco Unity documentation does not specify that even if you are a Unity subscriber, you cannot deliver a secured message, unless you log into Unity.
If one Unity subscriber calls another Unity subscriber and the call is forwarded to the second subscriber's voicemail, the option to deliver the message as a secured message does not exist currently as part of the standard subscriber's conversation.
The first subscriber must log into Unity, then dial the other subscriber's extension to access the conversation option for secured message delivery.
Cisco Unified CallManager Express Call Forwarding Problem
In Cisco IOS Release 12.3, the Call Forwarding feature works without the call-forward pattern parameter being configured under the telephony-service configuration mode.
When upgrading the IOS image on the Cisco Unified CallManager Express (CME) from IOS 12.3 version to 12.3(12) or above, you must configure the following parameter under telephony-service to activate the Call Forwarding feature:
where .T specifies the default of a wildcard match of any length or can be substituted by a string of digits with a specific desired pattern.
Use the Bug Toolkit to refer to related information (CSCeg07593), where the earlier IOS version used H.450.3 to forward the call in the absence of the above required configuration.
Changes to Cisco Emergency Responder Administration Guide
On pages 2-3 through 2-13 in Chapter 2 of the Cisco Emergency Responder Administration Guide, substitute all occurrences of the words "publisher" with "primary server" and "subscriber" with "secondary server".
Permissions on the Voice Connector Service in Cisco Unity Bridge
Permissions configured in the Domain Admin, Domain Users, and Exchange Administrator groups for the Cisco Unity Exchange Voice Connector can override similar permissions set at the local system account level.
For example, if explicit DENYs are configured in the above groups, they can prevent logging into the mailbox created for the AvExchangeIVC_<ServerName> object, even though no explicit DENYs are defined on the local system account.
DSCP Values Incorrectly Marked through NM-HDV
Symptom: When using an NM-HDV for conferencing or transcoding, DSCP values are marked with a value of 44 instead of the expected value of 46 (ef).
Conditions: In general for Quality of Service (QoS), all Cisco voice components should mark DSCP as "ef" when they transmit RTP/IP traffic. NM-HDV has a feature limitation, which prevents it from marking RTP/IP traffic with a DSCP of "ef" when it is used as a conference call bridge.
Workaround: Mark the packets using class-based marking (based on port range 16384-32767) and apply on the outbound interface as follows:class-map match-all matchipmatch ip rtp 16383 16383policy-map ippolicyclass matchipset dscp ef
You can also use other methods, such as "auto qos untrust," to mark RTP/IP packets as DSCP=ef.
Table 5 lists caveats, which are resolved now but the fix may not be included in the recommended component versions of IP Communications System Test Release 4.4 for North America IP Telephony. To determine the version of the software in which the fix is included (in the First Fixed-In Version field), click on the Identifier of each resolved caveat. You will be taken to the Bug Toolkit information for that caveat.
Table 6 lists known caveats related to the testing of IP Communications System Test Release 4.4 (and previous releases) that were not resolved at the time of this recommendation.
