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.
