try something like:
if
(method=="BYE" || method=="CANCEL") {
unforce_rtp_proxy();
if (method=="CANCEL")
t_relay();
exit;
}
be doing this you let the BYE to reach the loose_route and be properly
routed.

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.
