Abstract
A method and apparatus for controlling end-to-end media on packet networks such as Voice over Internet Protocol (VoIP) and Service over Internet Protocol (SoIP) networks are disclosed. The present method provides an algorithm to be run by channel terminations such that the media channel is controlled by compositional actions. For example, the servers that terminate the media channel are able to respond on behalf of an endpoint in order to effect the appropriate compositional action. The present method also enables each direction of a bi-directional media channel to be controlled independent of the media channel in the opposite direction.
