Just a guess, but I suspect that this might be related with strictrtp setting in rtp.conf, which learns the correct source in doing so drops a few packets. I would try to disable strictrtp for testing purposes and if this works add some delay before playing back the media.

Instead of hearing the full sequence of tones I hear a short ringing then part of the sequence. What seems odd is that I can see the telephone-event/8000 being passed up the chain but when it gets to Asterisk, it is never sent back to the phone. Instead I just see the usual RTP flows. I've been trying to fix this for hours, does anyone have any ideas how to get this working correctly? Asterisk version is 13.25.0 The settings I think are relevant (I'm using chan_sip): (sip.conf) ignoresdpversion=yes internal_timing=yes progressinband=never silencesuppression=no prematuremedia=no (Per peer) progressinband=yes directrtpsetup=no dtmfmode=rfc2833 directmedia=no silencesuppression=no prematuremedia=no TIA Mark. -- Mark Farmer [email protected]<mailto:[email protected]>
