I'm trying out sipML5 ( http://code.google.com/p/sipml5/ ) with FS and I had a problem with their demo. Their code uses a=crypto lines on RTP/SAVPF and FS is bouncing it with: 2012-05-21 13:04:47.754843 [ERR] sofia_glue.c:4478 a=crypto in RTP/AVP, refer to rfc3711 The crypto line is in RTP/SAVPF, though, not RTP/AVP. Is this line coming up because it's not RTP/SAVP? Am I missing a module for RTP/SAVPF, or is this even supported? Following is a trace -- I'm calling x7779 on my server which just plays a voice prompt.
