This document provides the i3 forum`s perspective on the interoperability issues related to the international interconnection of multiservice IMS-based platforms focusing on voice and video services originated from fixed as well as mobile networks. The scope covers both the interoperability between a Service Provider and Int. Carrier and between two Int. Carriers.
It does not intend to duplicate other existing specifications or documents on the same issue, but to complement these documents with the perspective of the International Carrier members of i3 forum.
