| Zusammenfassung: | The present invention provides methods, systems, and apparatus that allow at least two end-point IP telephony devices to synchronize multiple data streams conforming to mutually-exclusive signaling protocols into a single video telephony connection. An audio-only data stream conforming to an audio-only signaling protocol (such as PacketCable NCS) is combined with at least one video data stream conforming to one or more video signaling protocols (such as SIP or H.323) to produce a single IP telephony connection. Methods, systems, and apparatus are provided to establish an audio portion, a video portion, and optional data stream portions of a single IP telephony session. |
