Configuring the MOH Audio Source to Enable Multicasting
The MOH audio source is a file from which Cisco Unified CM transmits RTP packets. You can create
an audio file or use the default audio file. For Cisco Unified SRST multicast MOH, only one audio source
can be used, even if, for example, one out of 500 sites uses Cisco Unified SRST multicast MOH. In
addition, all Cisco Unified Communications Manager systems must use the same audio source for user
and network MOH because Cisco Unified SRST multicast MOH can stream audio only to a single
multicast IP address and port. For Cisco Unified SRST multicast MOH, the Cisco Unified
Communications Manager audio source file must be configured for G.711 bandwidth.
