Hey all! I recently tried the dtmf_mode "auto_info" on my setup to support endpoints that only understand SIP INFO as a fallback.
My setup is the following: Endpoint A (RFC4733) --> Asterisk <-- Endpoint B (SIP INFO) Both are configured with "auto_info" dtmf_mode in pjsip.conf. What I ran into is, that DTMF sent from endpoint A to endpoint B is additionally sent via inband audio on the RTP stream from Asterisk to endpoint B, as one can clearly hear the DTMF tone in the audio stream, when a capture is played back on Wireshark. On the leg from endpoint A to Asterisk there is no inband DTMF signal in the RTP audio stream. Can someone confirm this behavior? If yes than this is clearly a bug. I had a look in the code which introduced this feature and couldn't find anything obvious why this is happening.
