My understanding is that loose_route() checks for a
Route header field. The
standard cfg entry will then relay the SIP request.
Let's take the following scenario. I have a PSTN gateway which listens on
port 5060 and accepts to that port only from my SIP proxy. Normally the
proxy takes care of authentication and authorization and if approved,
forwards to the gateway. What if someone were to send an INVITE to my proxy
with a header: Route: <sip:phone-number@pstn-gateway>? Would the proxy
forward it, and the gateway then set up the call?
i call loose_route() in the beginning of ser.cfg before the user is
authenticated and approved for pstn access.
