asterisk users - Mar 2012 - No compatible codecs, not accepting this offer

For a few days now I'm getting

"chan_sip.c: No compatible codecs, not accepting this offer!"

on the CLI and in the messages log in irregular intervals. How can I 
find out what (who) is causing this? If I turn on "sip debug" I get 
flooded with SIP messages from peers/users (qualify=yes etc.) and it's 
hard to analyze.

Thanks!

HI,
Instead of taking traces on asterisk console, try capturing traffic in pcap
using tcpdump command  and later analyze it with wireshark.
#tcpdump -i eth*N *-s 0 -w sip-capture.pcap -v
Download this file to any machine with wireshark installed and apply
"sip"
as filter there.
Regards.
Sammy
