Summary:                    No voice joining snom 190 through asterisk to cisco
voice gateway occationally.
Description: 
Hello

I have a asterisk 1.4.17 box which I have configured to troubleshoot case
12708 and while it resolves that issue, I have come across a concerning bug
that has now occured 3 times in 1.5 days of testing. 

I have a snom 190 talking to asterisk via sip, talking to a cisco voice
gateway via sip. Everything is in realtime talking via odbc and freetds to
a mssql db. 

Calling out works fine most of the time however occationally (3 times)
when I call, the call connects, but no voice traverses in either
direction.

I will attach two sip debugs as I was able to catch it in action, but
please note that rtp debug and rtcp debug was not turned on until part way
through on the broken one. 

Things I noticed: when the first "invite sip" occurs on the broken one, it
does not pass media  or media atributes. Later on it adds ilbc to the
supported codecs and sets mode to 30ms.
