Method and system for monitoring and recording voice from circuit-switched switches via a packet-switched network
First Claim
1. A method for monitoring telephone calls handled by a circuit-switching switch coupled to a packet-switch network via a first voice over Internet Protocol (VoIP) telephony gateway and to a public switched telephone network, the method comprising:
- receiving by a recording system via the packet-switch network a computer telephony integration (CTI) datum associated with a telephone call handled by the circuit-switching switch; and
if the CTI datum meets at least one predefined monitoring condition;
sending instructions to establish a VoIP session between the first VoIP telephony gateway and a second VoIP telephony gateway coupled to the recording system, wherein the instructions are sent from the recording system;
sending instructions from the recording system to the circuit-switching switch to deliver packets of audio associated with the telephone call to the first VoIP telephony gateway coupled to the switch; and
receiving by the recording system via the packet-switch network at least a portion of the telephone call.

Abstract
Some embodiments of the present invention are directed to a method and system for monitoring and recording voice from circuit-switched switches via a packet-switched network. A circuit-switched or VoIP recording system may record and/or live-monitor telephone calls by trunk and/or extension tapping over a packet-switched network. Alternatively, a circuit-switched or VoIP recording system may record and/or live-monitor telephone calls over a packet-switched network by activating the service observation feature of the circuit-switched switch either by feature code dialing or a computer telephony integration (CTI) link command.

9. A method for monitoring telephone calls handled by a circuit-switching switch coupled to a packet-switch network via a first voice over Internet Protocol (VoIP) telephony gateway and to a public switched telephone network, the method comprising:
-
receiving by a recording system via the packet-switch network a real-time call detailed record (CDR) datum associated with a telephone call handled by the circuit-switching switch; and if the CDR datum meets at least one predefined monitoring condition; sending instructions to establish a VoIP session between the first VoIP telephony gateway and a second VoIP telephony gateway coupled to the recording system, wherein the instructions are sent from the recording system; sending instructions from the recording system to the circuit-switching switch to deliver packets of audio associated with the telephone call to the first VoIP telephony gateway coupled to the switch; and receiving by the recording system via the packet-switch network at least a portion of the telephone call. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
