The idea is that you have two different kinds of URIs, Contact URIs owned by a user-agent and AoR URIs, which are URIs owned by a proxy. When you register, the registrar binds a contact URI with AoR. While the registration is valid, proxy forwards the incoming request which have AoR as request-URI to the registered contact URI. Or to be more precise, one or more of the registered contact URIs selected by proxy's internal routing logic. Which makes them one of the most brain-damaged inventions in SIP. The From URI in REGISTER is usually just ignored by proxy, or it is checked that it is same as the To URI. > Hmm.. so what's the need to NUTAG_IDENTITY then if NUA can automaticaly > deduce the correct local contact details from existing nua_register > calls? You may want to make anonymous calls (using From: <sip:[EMAIL PROTECTED]>). Or an incoming calls might have got redirected, so the To header contains someone else's URI. >From and To URI are about as reliable indicator about the real sender and destination as in e-mail.
