I'm working through one of those lovely DTMF issues and have notice that a particular CPE that is experiencing a DTMF fault on our network sends both rfc2833 rtp packets _and_ the tone in audio stream (not named rtp packets, but how the device has 'heard' the tones from the originating handset).
Out of curiosity, how did you arrive at this conclusion? If you play back such a stream in, say, Wireshark, it will generally inject some sort of acoustic tone when it encounters the out-of-band named events. -- Alex Balashov - Principal Evariste Systems LLC 260 Peachtree Street NW Suite 2200 Atlanta, GA 30303 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/
