[Freeswitch-users] Translating DTMF from RFC2833 to INFO

[Yehavi Bourvine]

Hello Ognjen,

  From the tests I've done it is not so... When I set the profile to use
INFO, and a phone calls and asks for RFC2833 (phone-events in the SDP) the
FreeSwich ignores it (does not have phone-events field in the reply SDP)
which causes the phone to not send RFC2833 events...

                       Regards, __Yehavi:
