Abstract: Verification of Caller identification, used independently of caller ID or as an adjunct to caller ID for caller verification by matching caller voice samples to voice samples previously stored. Verification algorithms can be implemented as a stand alone device connected to the telephone line or the interne, in software which can be a resident on a PSTN phone, mobile phone or an IP phone or resident on a computer. Voice samples of the current caller are recorded and compared a database of previously recorded voice samples. When a call is received for the first time, the caller records the caller's name which is stored into a database and correlated with the received caller ID information of the present caller, if such information was received. If no caller ID information is received, the voice sample is stored in the database with an indication of a lack of caller ID information. The collection and storage of voice samples allows the use of such samples for voice authentication if the caller calls again.

Abstract: A router includes a transceiver operable to transmit and receive packets when operably connected to a communication network, and a processor cooperatively operable with the transceiver. The processor is associated with a unique network routable value and/or a physical address. The processor is configured to facilitate receiving a packet in accordance with the transceiver. The processor checks the packet for an indication to determine if the unique network routable address value and/or the physical address are to be inserted in a router location information field in the packet. If the packet has the indication, the processor inserts router location information indicative of the unique network routable address value and/or the physical address in the packet. The processor transmits the packet in accordance with the transceiver.

Abstract: A network infrastructure device in a voice over packet (VOP) network includes a transceiver and a processor. The transceiver can transmit and receive communications over a VOP network. The processor, responsive to receipt of a call setup information request (CIReq) specifying a particular target, can associate a public identifier with the particular target, and map the public identifier to an internet protocol (IP) address responsive to a communication. Also, the processor can identify communications to and/or from the particular target with the IP address. Further, responsive to receiving communications to and/or from the IP address, the processor can transmit the communications to a law enforcement agency (LEA) collection device.
