Hi,
I have a situation where MoH unable to playout for some reason when call coming from outside call to IP Phone. After I remove the MoH wav file and multicast and reapply to the router config, the MoH is working again.
External call --> ISDN PRI --> CCM (CTI RP) --> User Agent on hold (External caller unable to hear MoH)
Any suggestion where the problem is?
Thanks
