After further testing I have confirmed that is indeed the IOS version that
is not allowing for the Multicast MOH over a SIP trunk to a PSTN
Termination.
Tested versions:
c2801-adventerprisek9_ivs-mz.124-20.T4.bin = PSTN MOH DOESN"T WORK
c2801-adventerprisek9_ivs-mz.124-22.T.bin = PSTN MOH WORKS
Am I correct in my testing that Multicast over SIP trunk to a PSTN
connection doesn't work? (I hear dead air and my
MOHMulticastResourceActive = 1 ) I have the following setup and I am
unable to get PSTN MULTICAST MOH to work correctly, but Internal clients get
MOH. I have tested with and H32
