A method for call signaling and media flow in a network including receiving call signaling information from an originating Voice over Internet Protocol (VoIP) endpoint relaying the call signaling information to a destination VoIP endpoint, directing the originating VoIP endpoint to use a RTP media proxy and receiving a stream of media to the RTP media proxy from the originating VoIP endpoint.

Voice over internet protocol real time protocol routing

A telephone system supports communication with user devices over both a cellular radio network as well as over an Internet Protocol (IP) network, and enables roaming and active call handoff between cellular and IP domains. Approaches to detecting presence of a user near a suitable IP network are used in controlling transitions between the domains, for example, enabling automatic transitions between domains, and delivery of calls to a mobile user to data network devices in the vicinity of the user.

Presence detection for cellular and internet protocol telephony

A method for call signaling and media flow in a network including receiving call signaling information from an originating Voice over Internet Protocol (VoIP) endpoint, relaying the call signaling information to a destination VoIP endpoint, directing the originating VoIP endpoint to use a RTP media proxy and receiving a stream of media to the RTP media proxy from the originating VoIP endpoint.

Voice over Internet Protocol real time protocol routing

Routing calls through networks includes a device configured to support a first protocol for initiation, maintenance, and termination of a communication session between call endpoints, and to support a second protocol for resolving endpoint addresses for the communication session.
