New subject: [Users] UA not receiving BYE from SPA 3000

27 Jun 2006

Hi Bogdan,
   Thanks for the reply. I'm still somewhat lost on the second point you told me.

...
 Second, BYE is an within the dialog request so you need
to do 
loose_route() for it, Just relaying it based on RURI is not correct at 
all. 

Does that mean in my loose route I have to have something like this:

If(method=="BYE")
{
 route(1);
 exit;
}

Here is my updated openser.cfg. Also, am I suppose to exit after
a forbidden meesage or error messages? 
Or should I return? Please advise me. Thank you.
