We have following problem. We have an intercluster trunk connection to an IP GSM Gateway and we want to send DTMF tone over it. Problem is, that CCM is sending DTMF via H245 messages and not via tone. The IP GSM Gateway can?t interprete this. If I make this via Cisco Voice Gateway everything looks fine. Is there any possibility to send this DTMF inbound as voice tone?
Re: CCM 4.1.3 - DTMF via Interclustertrunk over H245
To activate DTMF on the call, ensure that it matches with an appropriate inbound VoIP dial peer with DTMF relay enabled. If no inbound dial peer is matched, then the default dial peer is used. In this case, DTMF will not be activated for the call, since the default dial peer does not have DTMF enabled
