[Freeswitch-dev] SIP Timeout waiting for 200 ACK

[Mike Murdock]

I am dealing with the same problem... Brian, there is something wrong here. The effect is my calls get terminated every two minutes +hen my sipura re-registers. I have a trace with full debug captured if you want to see.

I think that since we are a B2BUA tech_pvt->profile->url is the right  
way.  The other way is correct if you're a proxy.  Remember  
FreeSWITCH NOT a proxy.
