SIP

If the customer-next-hop parameter points to a SIP session agent or the SIP session agent group, the Oracle Communications Session Border Controller creates a Route header using the session agent and modifies the Request-URI. It changes the user portion of the Request-URI to either the user portion of the P-Called-Party-ID header, if present, or to the user portion of the To header. The Oracle Communications Session Border Controller also changes the host portion of the Request-URI to the hostname configured in the customer-host configuration parameter. It makes the change because the domain name on the core side can be different than the domain name on the access IP-PBX side. The Oracle Communications Session Border Controller then uses the added Route header to properly route the call.
