Description (last modified by bennylp)

The incoming RFC 2833 DTMF handler does not handle the case where RTP packets arrive out of order. In this case, the packets may cause stream.c to detect them as multiple DTMF events.

Attachment dtmf.patch:

  • Added new API pjmedia_rtp_session_update2() which behaves like pjmedia_rtp_session_update() with additional option to validate payload type
  • Changed in stream.c:
    • replaced pjmedia_rtp_session_update() with pjmedia_rtp_session_update2(), so the RTP session validation will avoid payload type checking when received PT == DTMF event PT
    • moved handle_incoming_dtmf() from before to after pjmedia_rtp_session_update2()
