Claim:
1. A communication system for effecting communication events between a plurality of endpoints connected via a communication network, the communication system comprising: one or more processing units having access to computer storage holding executable code modules for managing a communication event, the code modules configured to implement a media modality controller configured to manage media modality of an established communication event and a call controller configured to establish the communication event; wherein an instance of the media modality controller is assigned to convey media modality control signals of the communication event to respective media modality agents of the endpoints without accessing respective call agents of the endpoints, the media modality controller instance being so assigned independently of the call controller and responsive to an instruction received via the network; and wherein the media modality controller instance is released from said assignment responsive to the media modality controller instance returning a response to the received instruction while the call controller continues to operate in communication with the call agents of the endpoints.
