Hi all,
I am having a problem with DTMF in a Conference Bride.
This is the call flow.
PSTN FXO/PRI -> PSTN Router -> SIP Dialpeer -> CUCM -> SCCP Phone -> (Conference) -> (IVR) VXML Gateway.
The conference Bridge is the PSTN Router PVDM. this is the RTP audio flow.
PSTN CFB <-----> VXML (IOS) Gateway
When the 3 people (caller, called and IVR) are in conference, PSTN caller press digits but IVR does not recognize it, but we are able to hear the DTFM tones.
We use rtp-nte in out SIP Dial-peer --> CUCM.
How can the CFB Device send DTMF to VXML IOS GW? (its audio is point to point). is the CFB suposed to MIX the RTP NTE and send DTMF?
Juan.
