Abstract: Devices, methods, systems, and computer-readable media for using network connection health data, from multiple sources, to determine whether to switch a network connection on redundant IP networks using VoIP protocol are described herein. One non-transitory computer readable medium includes instructions for connecting an end device used by a first party to communicate with a second party through a VoIP network connection via a VoIP network device, connecting a first network device operating a first network to the VoIP device, connecting a second network device operating a second network to the VoIP device, if there are indications of a fault on at least two OSI layers, then switching from communicating VoIP connection related packets of data on the first network to communicating the VoIP connection related packets of data on the second network.

Abstract: Devices, methods, systems, and computer-readable media for using connectionless loops for monitoring data link health using connectionless loops over redundant Internet Protocol (IP) networks are described herein. One system includes an IP network device connected to a device used by a party to communicate with another party through an IP network, a first network device operating a first network and referring to the IP network device with a first identifier, a second network device operating a second network and referring to the IP network device with a second identifier, an intermediary device allowing communication between the first and second networks, and instructions to create a connectionless packet, send the packet through the first network addressed to the second identifier, such that the packet is routed from the first network to the intermediary device and into the second network based on the second identifier, and receive the packet.

Abstract: In one embodiment, a method includes sending, from an originating gateway device (OGW) to a terminating gateway device (TGW), a setup message for setting up a call on a primary bearer channel (B-channel) of an Integrated Services Digital Network (ISDN). The OGW interconnects with a first Internet Protocol (IP) video endpoint, and the TGW interconnects with a second IP video endpoint. In response to an alerting message sent from the TGW, the OGW initiates procedures for synchronizing a plurality of secondary B-channels between the OGW and the TGW prior to the call entering into a connect state. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.

Abstract: In one embodiment, a system includes first and second gateway devices operable to communicate with respective first and second video terminals in accordance with H.323, the first and second gateway devices also being operable to communicate with each other over an H.320 call leg. Responsive to a first message received from the first video terminal that contains a terminal capability in H.245, the first gateway mapping the terminal capability into a non-standard section of an H.221 data stream, and send the data stream to the second gateway device. The second gateway device decoding the terminal capability from the non-standard section, encoding the terminal capability in H.245 in a second message, and sending the second message to the second video terminal. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.
