This should have been done by pjmedia. pjmedia does retransmit RTP packets containing DTMF event, according to PJMEDIA_DTMF_DURATION setting (default is 1600, in timestamp unit). So for example with 8Khz codecs (g711, gsm, ilbc etc), each RTP event will be transmitted 10 times since each RTP packet has 160 timestamp duration (equal to 20ms). cheers, -benny
