I am using cvp 4.0 and ICM 7.2.3 the issue that we are facing is that when the call is being transferred to the agent no ring back is heard by the customer. I have checked the dial-peer the dial-peer for 91919191 is configured correctly we are using static routes in which 91919191 static route is pointed towards the gateway.
Can anyone please help me get to the Root cause of the issue?
The ringone dial-peer is only relevant to SIP deployments. H.323 has built-in methods to get ringback from the gateway or from the far end (CUCM), you may want to take a look at general VoIP ringback troubleshooting as documented here :
