Hello,

I'm working with start_dtmf in order to transcode inband DTMF to RTP-Event.

That's working fine but I'm wondering how could I check the B-leg SDP to match if there's or not "telephone-event" to do it only if require. That would also allow me to do RFC2833 to inband from A-leg to B-leg.

I can easily check ${switch_r_sdp} for A-leg, but I can't figure out how to check 200 OK SDP and update the DTMF behaviour accordingly.

Any idea? Thank you.

Regards,

Igor.
