摘要： 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.

摘要： Methods and systems for providing lawful intercept of a media stream in a media gateway include establishing a call context between a first termination and a second termination and establishing a tap context with at least one tap termination, which refer to the first termination. The call context defines a call media stream between the first and second terminations associated with a call between first and second end users. The tap context defines at least one tap media stream from the first termination to the at least one tap termination. The tap media stream is a one-way media stream that carries either the mouth portion of the call media stream, the ear portion of the media stream, or a combination of the mouth and ear portions of the media stream from the first termination to the at least one tap termination. Multiple tap contexts can be created to support the lawful intercept of the call by multiple law enforcement agencies.

摘要： The subject matter described herein includes methods, systems, and computer program products for providing TDM terminating services in a packet network. According to one method, a combined set including a plurality of TDM channels is received over a packet network. The combined set of TDM channels is terminated in the packet network as a combined TDM facility. Terminating the TDM channels as a combined TDM facility may include providing at least one terminating TDM service for the TDM channels, such as performing CAS signaling or providing a PRI interface for the TDM channels.
