摘要:
Surveillance of IP telephony may be performed through the use of conventional telephone equipment, according to principles of the invention while preventing giving indication to the monitored phone by alerting the user of the monitoring phone to such surveillance use prior to pick up by an agent for engagement of the monitoring phone in response to the alert. Such alerts may assume many forms such as ringing, visual indicators, data readouts, activating ancillary equipment, various flags, etc. This alert prior to surveillance is distinct from alerts used for normal non-surveillance calls, which the monitoring phone is capable of receiving.
摘要:
Surveillance of IP voice calls over a public communication IP link is achieved by a WatchDog program, associated with an IP Address Mapping Check Point translating IP phone numbers into IP addresses, that are connected to a head end hub connected in turn to a Hybrid Fiber Coax (HFC) link of IP phone users or to a backbone network carrying IP voice packets.

摘要:
Monitored calls are intercepted and rerouted to a changed location number of a called party while appearing to be at the same directory number by intervention of an IP Address Mapping check Point (IP-AMCP) which duplicates the voice to a monitoring location, automatically identifies the types of networks to be traversed to the new location and adapts the duplicated voice message to traverse such network types. Surveillance is enabled to be conducted at more than one monitoring location each of which many are widely separated from the other.
摘要:
Monitored calls are intercepted and rerouted to plural selected monitoring stations by intervention of an IP phone monitor center (IPMC) which duplicates the voice to a monitoring location and automatically identifying the types of networks to be traversed and adapting the voice message to such a network type to communication with monitoring stations connected to these networks. Surveillance is, therefor, enabled to be conducted at more than one monitoring location each of which many are widely separated from the other. In a particular embodiment an authorized surveillance agent transmits a valid request to an IP phone monitor center (IPMC) which in response intercepts voice packets to and from the targeted IP phone. The duplicated voice packets are transmitted to the designated monitoring location. The IPMC determines the type of voice signal to be transmitted to the terminal monitoring station. If the monitoring location is serviced by an IP telephony network the monitored traffic is duplicated by the IP-AMCP in IP format to an IP DN as programmed by the IP-PIL. If the monitoring location is serviced by a PSTN network a PSTN check point (PSTN-CP) establishes a trunk connection with the local directory service (LDS) and receives incoming voice packets at the IP-AMCP which the PSTN-CP converts to voice trunk (i.e., T1) to communicate with the LDS.
摘要:
A monitoring network is able to provide surveillance of IP phone calls, which span plural backbone networks, which may embody different transmission techniques. An agent connected through a monitor center to one backbone network enters a request for surveillance (i.e. wiretapping) of a particular network connected to another backbone network. A WatchDog program is associated with each backbone network. These WatchDogs all communicate with other watchdogs associated with other backbone networks. All these watchdogs interact with one another to set up the surveillance connections. The watchdog of the requester's backbone network receives the surveillance request and flows/transmits the request to a watchdog function of the terminating backbone network of the specific caller to be monitored establishing a point-to-point connection, through as many backbone networks as needed. The terminating WatchDog of the termination backbone network flows/transmits the request to a destination WatchDog associated with an IP address mapping checkpoint of the target telephone number to be surveillanced. The destination watchdog communicates with the requesting WatchDog using predefined protocols spanning the intervening backbone networks. The destination WatchDog replicates the packets of the target telephone and transmits them to the originating monitor center.
摘要:
A method and apparatus for providing multiple telephone lines using a single directory number. A method and apparatus for associating multiple directory numbers with multiple telephone lines. A broadband residential gateway (BRG) is a user interface to a broadband communication system providing packetized telephone service and other media services. The BRG has multiple ports, and each port is connected to one or more telephones. The multiple ports may be mapped to a single directory number, or the multiple ports may be mapped to multiple directory numbers. The BRG can provide greeting and message features. A greeting may instruct a caller to select a port which is associated with a party the caller is attempting to reach. Also, a message, played after the greeting, may further instruct the caller.
