Abstract: Caller ID information provided coincident to a Voice over IP (VoIP) call is validated by one or more network devices. An originating router detects an offered IP address associated with a calling party node, for example, upon receiving a SIP Invite message initiated by the calling party node. The originating router determines the validity of the offered IP address and hence determines the validity of the Caller ID information based on the validity of the offered IP address. The originating router sends indicia of the validity to a terminating router, connected to a called party node, by inserting a verification bit in the SIP Invite message and sending the transformed SIP Invite message to the terminating router. Alternatively, the terminating router may query the originating router for indicia of validity. Upon receiving the indicia of validity, the terminating router may notify the called party node and so inform the called party whether it can rely on the Caller ID information.

Abstract: A method and apparatus for surveillance of voice over Internet protocol (VoIP) communications is provided. A server (112) associated with a network provider receives information to identify communications associated with a party under surveillance (200). The server uses the information to direct communications associated with the party under surveillance to a surveillance server (130) (202). The communications are analyzed to identify any initial VoIP data (204). If initial VoIP data is detected, identifiers for subsequent related VoIP communications are determined from the initial VoIP data (206). The identifiers for subsequent VoIP communications are used to identify subsequent VoIP packets. Those subsequent VoIP packets are then stored and analyzed as needed by an agency conducting surveillance.

Abstract: The present invention provides a method for notifying a primary wireless unit in a group calling plan that a wireless unit in the group calling plan has call activity. An MSC determines if there is call activity on a wireless phone. The MSC determines if the wireless phone is a member of a call monitoring group. If so, the MSC records call information related to the call activity and sends the call information to the primary wireless unit.

Abstract: An apparatus in one example comprises a server component that sends one or more signals to cause an allocation of one or more network resources for an active call terminated to a mobile telephone upon initiation of a handoff. The handoff is between a packet-switched portion of a mobile switching center and a circuit-switched portion of a mobile switching center. The one or more network resources provide a translation between the packet-switched portion of the mobile switching center and the circuit-switched portion of the mobile switching center.

Abstract: A system and method of routing calls made to a called party Universal Access Phone Number (UAPN) in a telecommunications network is provided. The method includes determining the time the call is made, determining the day the call is made, selecting a time/day-phone number for a destination phone number based on the time the call is made and the day the call is made, and routing the call to the called party terminal using the destination phone number. The system selects a time/day-phone number for a destination phone number based on the time the call is made and the day the call is made, and routes the call to the called party terminal using the destination phone number.

Abstract: Embodiments of the method and system provide for providing a call waiting method for use in a telecommunications network in which a first caller is engaged in a current call with a second caller, and for processing an incoming call from a third caller to the first caller.

Abstract: A method is provided for fax call blocking. The method includes: receiving a first call intended for an end instrument (10) employed by a user; obtaining a telephone number from which the first call originated; comparing the obtained telephone number against a first database (42) to determine if the obtained telephone number matches a blocked telephone number contained in the first database (42); blocking the first call such that the end instrument (10) is not alerted if a match is found between the obtained telephone number and a blocked telephone number, otherwise providing a connection to the end instrument (10) for the first call; monitoring the connection to detect for fax tone; and, entering the obtained telephone number in the database (42) as a blocked telephone number if fax tone is detected.

Abstract: In response to a mobile subscriber station to mobile subscriber station call, the intelligent coding process transmits data during the call setup process from the originating mobile switching center to the mobile switching center that serves the called party, indicative of the characteristics of the originating end user device and the coding processes in use at the originating end user device. The intelligent coding process also signals the inter-mobile switching center network to indicate that this call connection does not require the use of a vocoder in the network transmission of the call. The inter-mobile switching center trunks then pass the coded data received from the codec in the originating mobile subscriber station to the mobile switching center that serves the called party, where the coded data is transmitted to the mobile subscriber station of the called party. The codec in this mobile subscriber station performs the speech decoding necessary to transmit the data to the called party.

Abstract: Service provider flexibility in wireless network configuration is enhanced by first and second interconnection protocols which enable flexibility in mobile switching center/base station communications. This communication flexibility allows service providers to control, on a call-by-call basis, the operation of the wireless telecommunications network.
