Abstract:
A call processing method and system in which the use of the MGW between the RNC and the peer party is limited to only certain situations. This invention uses RFC 3267 (AMR/IETF) on the RNC. This will avoid inserting a MGW context for framing conversion only. This invention provides an optimization that sets up calls from the RNC, thus avoiding the need for a MGW in the path for basic calls. With this optimization, the usage of DSP and packet resources and the number of MGW chassis, as well as bearer path delay, are all reduced.

Abstract:
An apparatus in one example has: a plurality of networks operatively coupled to one another, and having respective end points; and a single SIP (Session Initiation Protocol) profile useable by each network of the plurality of networks; wherein two end points, via signaling mechanisms within SIP, negotiate a level of support for ISUP (Integrated Services Digital Network User Part) services that are usable between the two end points.
