In IMS context, While forwarding a REGISTER message, the P-CSCF includes its own URI in the 'Path' header to inform S-CSCF where to route the terminating requests. This value is stored by the S-CSCF.
On the other hand, 'Service-Route' is inserted by S-CSCF in the 200 OK response to REGISTER. This header contains the S-CSCF URI along with a string ( usually "orig" ). This is usually used to differentiate between originating and teminating requests. When received, the P-CSCF stores this Service-Route header value and associates it with the UE. -- Regards, Hema Ramesh.
