I am trying to get Freeswitch to work with my SIP provider, IP24, but I always get very bad sound in one direction. I made a wireshark trace, and looked at the jitter graph it produced. I made an incoming call from my mobile phone to Freeswitch via SIP provider IP24, PCMA codec: 1. http://www.myrvold.org/freeswitch/me2ip24.jpg , from freeswitch->ip24 2. http://www.myrvold.org/freeswitch/ip242me.jpg , from ip24->freeswitch There is a big difference in jitter between the two graphs, and the speech quality is very bad ip24->freeswitch (2). What can I do to fix the speech quality? Asterisk and OpenPBX (CallWeaver) have both excellent audio quality in calls through my SIP provider IP24. Here is a voip graph of the SIP call: http://www.myrvold.org/ freeswitch/graph.jpg Ivan
