Appendix B: Integrating Cisco Unified Communications Manager and Cisco Unified SRST to Use Cisco Unified SRST
Multicast MOH for H.323 and MGCP is supported on Cisco Unified CM 3.1.1 and higher versions.
Cisco Unified CM must be configured as follows:
With multicast MOH enabled.
–
With Media Resource Groups (MRGs) and Media Resource Group Lists (MRGLs) controlling
–
which devices receive multicast MOH and which devices receive unicast MOH.
With Cisco Unified CM regions assigned so that G.711 is used whenever a Cisco Unified SRST
–
multicast MOH resource is invoked.
The Cisco Unified SRST gateways must run on Cisco Unified SRST 3.0 on Cisco IOS
Release 12.2(15)ZJ2 or a later release.
Cisco Unified CM and Cisco Unified SRST must run on either H.323 or MGCP.
For branches that do not run Cisco Unified SRST, Cisco Unified CM multicast MOH packets must
cross the WAN. To accomplish this, you must have multicast routing enabled in your network. For
more information about multicast routing, see the "IP Multicast" section of
Configuration Guide, Release
With Cisco IOS earlier than 12.3(14)T, configure Cisco Unified SRST as your MGCP gateway's
fallback mode using the ccm-manager fallback-mgcp and call application alternate commands.
With Cisco IOS releases after 12.3(14)T, the ccm-manager fallback-mgcp and service commands
must be configured. Configuring these two commands allows Cisco Unified SRST to assume control
over the voice port and over call processing on the MGCP gateway. A complete configuration
describing setting up Cisco Unified SRST as your fallback mode is shown in
Communications Manager Administration Guide, Release 5.1(3) Survivable Remote Site Telephony
Configuration.
Cisco Unified SRST multicast MOH does not support unicast MOH.
Only a single Cisco Unified CM audio source can be used throughout the network. However, the
audio files on each Cisco Unified SRST gateway's flash memory can be different.
Cisco Unified SRST multicast MOH supports G.711 only.
Multicast MOH support for H.323 is unavailable in all versions of Cisco Unified
Communications Manager 3.3.2. For more information, see CSCdz00697 using the
In the Cisco IOS Release 12.2(15)ZJ image for Cisco 1700 series gateways, Cisco Unified SRST
multicast MOH does not include support for H.323 mode.
