¿µ¹®³»¿ë¿ä¾à This Recommendation contains a service-level profile, i.e. SIP/SDP interface description, between two network operators (NNI signalling profile), where the two different network operators may support different SIP/SDP profiles (i.e. they differ in terms of the SIP extensions, SIP information elements, and SDP lines which are supported). Transport-level profile, e.g. RTP, is described, as necessary as the media are described in the service-level signalling.
