[Serusers] Interdomain remote disconnect - sr-users

15 Dec 2006


      Hi,
I've a following problem: I'm dialing over voip to another domain. 
Everything swings except that when a remote party hangs up, I don't get 
a disconnect signal at my caller. Instead I'm getting ". I'm pretty sure 
I messed up something with my force/unforce proxy but I just can't get 
it working right. Note that when I'm calling to the PSTN (same transit 
proxy) through Asterisk I do get the disconnect signal. Any help would 
be appreciated :). Below is the config of my local proxy. I can post my 
transit proxy conf if needed.
Thanks,
Maciek
