摘要： A method and apparatus for handling persistence measurement of channel associated signaling for a plurality of line circuits, eg, T1, E1, OC3, STM 1 circuits, which extracts channel associated signaling data from a plurality of line circuits; assembles the channel associated signaling data into a data frame; contains the data frame in a suitable carrier, eg, an AAL 0 cell; monitors a continuous stream of the data frames, to check for changes in line status; and generates an event message data frame when a persistent change of line state has been detected. The extracting of associated signaling data may be provided on a separate card to a call control processor, and using separate processor functionality. A data processing load of a prior art call control processor which would otherwise be taken up in channel associated signaling persistence measurements may be alleviated, and the data processing burden on a prior art call control processor for handling persistence measurements is separated off and handled by the data processing apparatus and method according to the present disclosure.

摘要： Disclosed is an apparatus for providing an absent addressing service (i.e. call forwarding, voice messaging, and the like) for subscribers normally connected to a H.323 compliant network. Some network entity, such as a subscriber's gatekeeper, intercepts all set-up calls to subscribers requiring such a service. If the subscriber is properly registered, the set-up call is forwarded to the subscriber. Otherwise messages are delivered, in accordance with the configuration of the network gatekeeper, whereby the calling party becomes connected to an absent addressing service rather than the originally called terminal of the subscriber.

摘要： An Internet Protocol (IP) voice telephony system constructed according to the present invention manages Gatekeeper load by redirecting calls from an assigned Gatekeeper to a servicing Gatekeeper during call setup. A Load Management Unit (LMU) processes all setup messages. In processing the setup messages, the LMU receives the message from the assigned Gatekeeper to which a requesting endpoint is registered. Upon receipt, the LMU determines which Gatekeeper of a plurality of Gatekeepers should setup and service the call. Based upon its selection, the LMU either directs the assigned Gatekeeper to setup and service the call or redirects the endpoint to a servicing Gatekeeper. Upon receipt of a redirection message, the endpoint sends a confirmation message to the assigned Gateway and then sends a setup message to the servicing Gateway. Upon receipt of the setup message, the servicing Gateway sets up and services the call. In selecting the servicing Gateway, the LMU may consider loading on each Gateway, availability of each Gateway (e.g., are any Gateways out of service), and load distribution among a plurality of Gateways, among other consideration.

摘要： Disclosed is an method and apparatus for configuring an H.323 compliant data packet network with a registering function whereby home based users are identified separate from visiting users having other networks as home bases. Thus user location data may be retrieved and/or modified as those users roam to other H.323 compliant networks and register with a gatekeeper at that visited network. The registration of a visiting user with a visited gatekeeper includes the process of assigning a transient identity to the roaming user, obtaining confirmation from the home gatekeeper that roaming is authorized and registering the roaming users present address and transient identity at the home site so that calls received at the home network can be directed to the user at the visited site.

摘要： The present invention provides a technique for handling damaged named signal event (NSE) packets that are received in association with a voice over packet based telephony call. The received packets for a telephony call may include voice packets as well as NSE packets. Upon receipt of the packets at a physical layer, the packets are processed at a link layer to detect damaged packets having link layer errors. The incoming packets are sent to an audio application at an application layer for further processing. For damaged packets, link layer error indicia is generated at the link layer and sent to the audio processing application. The audio application will use the link layer error indicia to identify damaged packets or payloads associated with damaged packets, and determine whether the payloads corresponding to the damaged packets include NSE information defining an NSE. Damaged NSE packets are processed accordingly.
