Methods and systems for controlling media stream handover in a media gateway includes establishing a call context between a first termination and a second termination in a media gateway. The first and second terminations are capable of bi-directional media stream communications associated with a call between first and second end users. In response to a handover event affecting the first termination, a third termination is added to the context. The third termination is initially capable of receive-only communications. The context is then modified such that the third termination becomes capable of bi-directional media stream communications and the first termination becomes capable of receive-only communications. The first termination is then removed from the context. The media stream handover may be performed using extensions to a media gateway control protocol and without using a conference bridge.
