Hello,
I have problem, when I'm calling to IPCC IVR from non ip phone through VoIP device defined as H.323 gateway in Communication Manager 5.1 the DTMF digits are not recognized.
This gateway doesn't have capability of DTMF relay. In the same network I have Cisco mgcp gateways, DTMF digits coming from non IP phones through these gateways without problem. How to get it working together?
