I have multiple sites and works well the "SRST as a multicast MoH resource" via MGCP SRST gateway. remote IP Phone and PSTN call via remote gateway's PRI interface can get the MoH from local SRST router.
I have added one 3845 router in new remote site which has one PRI interface and "SIP trunk" to CUCM. The purpose of the router is to handle the PSTN call but no IP Phones which means no SRST. The requirement is the PSTN caller able to get the MoH from local 3845 router instead of CUCM.
There is two options for multicast MoH,
1) multicast MoH from CUCM and sends to remote gateway via WAN
2) multicast MoH from local SRST gateway.
As per CUCM SRND and IOS requirement, "Multicast MoH" supports from CUCM6.1.3 and IOS 12.4(4)T2 with the command "ccm-manager music-on-hold" in SIP trunk. I want to know what options referred for this.
Can I achieve option 2) in 3845 SIP gateway?
