Does anyone know if multicast MOH is supported when Cisco Communications Manager is configured to use an IOS software MTP for calls out through an IPIP gateway?
The scenario is as follows:
In this scenario early media is only supported by the VoIP SP on the SIP trunk so fast start has to be supported for outbound calls on the h.323 connection to the IPIPgw. The IPIPgw is configured as an h.323 gateway and also incorporates an IOS software MTP to allow h.323 fast start for outbound calls (rather than having it on CCM).
When a call out via the VoIP SP is placed on hold can multicast MOH be streamed to the IPIPgw or is there a limitation to using just unitcast MOH streams?
I am curious to know if anyone knows the answer.
