SIP Client Silence issue

Hi All,

I am getting silent error upon when b-party answer, we will get below error printed on asterisk shell and then silent. This is almost immediate when call is being answered

[color=#BF0000][May 25 17:52:00] WARNING[377]: chan_sip.c:8691 process_sdp: Insufficient information for SDP (m= not found)[/color]

Waiting for your kind and quick response.thanks

It looks like the SDP (which is part of few of the SIP negotiation) is bad formatted. I suggest to :

  1. Try different type of phone and see if the problem is solved.
  2. Turn on Sip Debug and check the SDP portion.

Thank you very much :smile: valer
