[asterisk-dev] confbridge DTMF

[Jason Ostrom]

Chandrakant,

It's my understanding that DTMF should be automatically detected on the conference if the SIP UA has correct DTMF mode, such as the following in sip.conf for peer:
dtmfmode=rfc2833

In ingress through SIP trunk your provider would have to properly relay through rfc2833 or SIP INFO.

The way I have been able to detect DTMF detection using confbridge is to configuring logger.conf to display DTMF on console, such as:
console => notice,warning,error,dtmf

In confbridge.conf you can have a simple menu to verify actions such as muting, etc., and this is how I have been testing menu responses as confbridge app detecting DTMF.

My issue is that I can't get DTMF relay/broadcast to work so that any DTMF digits entered are picked up by other conference users.  I think the setting is:
dtmf_passthrough=yes

Let me know if I can help further or if you figure out how to do DTMF Broadcast / relay to all conference participants.
