[pjsip] Incoming DTMF INFO

[Archie Rosenblum]

I have a quick DTMF question, if you please.  My client application is
receiving DTMF INFO from a server, but the on_dtmf_digit callback is not
triggered.  I have tested this with PJSUA (the debug screen is below).  The
PJSIP documentation mentions the system handles DTMF via RFC2833 and INFO,
but does not explicitely say the callback is triggers for both types of
messages.  The callback is called with RFC2833.

 

Should I expect the on_dtmf_digit to be called when DTMF INFO comes in, or
should I interrogate the INFO message for the application/dtmf-relay?

 

Sincerely,

Archie
