MOH works between IP phones but not between an IP phone and a PSTN phone. When put on hold holdee gets silence.
Loopback interface on the two MGCP Voice Gateways are not configured, but we have been adviced to put a loopback interface with a routable IP address on it to fix this problem. These routers each has a BVI40 interface which is in the same VLAN 40 as the CCM and we can confirm that the Multicast MOH stream is hitting the Voice Gateway.
These two Voice Gateways connect to CAT 6500 interfaces which are in VLAN40 same as the CCM.
We have the
command and this is where my question is.
Do we have to have the command
ccm-manager music-on-hold bind interface BVI40 command ?
We are using CCM version 4.1 and it is configured to send MOH Multicast and increment on Port Nummber rather than on IP address for the various codecs.
I have read all of the information at all of the links below and I can't still seem to find an answer. But the links are very informative in understanding MOH and MOH using Unicast and Multicast.
