Hi, this is not the correct question. A user is not a trusted node in the network (usually) so the user should just set the mandatory From header (and maybe the P-Preferred-Identity). Its outboud proxy is the responsible of asserting the identity of the originator (the user) and can append a P-Asserted-Identity or Remote-Party-Id header containing the asserted identity (AoR). The proxy should ignore and remove any PAI or RPID header in a request coming from a user (a NON trusted node). The proxy would then route the call to some PSTN gateway which trusts the proxy and uses the PAI or RPID value as call line identifier. NOTE: The RPID header is *NOT* a standard. It's widely used but a new deployment should move to the standard: P-Asserted-Identity. For more information about how all this stuf works, please read RFC 3325 in which *every* detail is fully explained. -- Iñaki Baz Castillo <[email protected]> _______________________________________________ Users mailing list [email protected] http://lists.opensips.org/cgi-bin/mailman/listinfo/users
