Abstract

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.
