[Users] ngrep explanation please - sr-users

18 Sep 2006


      I have a softphone (eyebeam at 7211) and I try to call a hard phone at 7112.
Eyebeam shows after the phone rang:
Call failed: Media negotiation failed.
I have set-up both for voice: G711u and video: h264.
Can you please brief explain me what I see with:
 ngrep -d any -qt port 5060
(output is below)?
(brief) and where do I get a detail information for it?
and what could be the problem, what could be a possible solution?
thanks for your help!
bye
Ronald
