has anyone any pointers on how to implement
interdomain
routing with SER _without_ using the domain part of an
uri when dialing.
Example:
I want to map sip:400000@mydomain (not only one id but a complete range)
to sip:400000@otherdomain.
"mydomain" is served via my Proxy server and otherdomain by someone else.
My first thought was to just rewrite the "to" part of the uri but AFAIK
thats not suggested because it violates the SIP RFC.
Am I being dumb or missing the point? Though you can't rewrite To:,
you can rewrite Request-URI - it's the SIP equivalent of being able
to rewrite envelope "TO" but not not header To: in SMTP. So you
rewrite **Request-URI:** sip:400000@mydomain to sip:400000@otherdomain,
and leave the To: field as it was. The proxy server downstream should
not be looking at To: (it should be looking at Request-URI) or things
like diversion and deflection to its users wouldn't work.
