Abstract
A method and system for establishing a call between two endpoints residing on different media gateways in a decomposed voice over packet architecture. Cluster attributes identifying alternate bearer possibilities are exchanged between media gateways as part of capabilities negotiation which occurs during call setup conducted by an external call control element over a core network. The media gateways analyze the cluster attributes to determine whether bearer possibilities exist apart from the core network. If an alternate bearer possibility exists, the alternate is employed and the call is established via the alternate bearer directly between the media gateways, thus bypassing the core network.
