Method and system for monitoring and recording voice from circuit-switched switches via a packet-switched network
View Patent ↗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.
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.
2. The method of claim 1 comprising:
recording at least the portion of the telephone call.
3. The method of claim 1 comprising:
performing live-monitoring of at least the portion of the telephone call.
4. The method of claim 1 comprising:
sending instructions over the packet-switch network to tap an extension line coupled to the circuit-switching switch; and
receiving, over the packet-switch network, audio data of telephone calls delivered over the extension line.
5. The method of claim 1 comprising:
sending instructions over the packet-switch network to tap a trunk coupled to the circuit-switching switch; and
receiving, over the packet-switch network, audio data of telephone calls delivered over the trunk.
6. The method of claim 1 comprising:
sending instructions over the packet-switch network to observe an extension line coupled to the circuit-switching switch; and
receiving, over the packet-switch network, telephone calls delivered over the extension line.
7. The method of claim 6 , wherein sending the instructions comprises dialing via the packet-switch network a code to perform a service observation of the extension line.
8. The method of claim 6 , wherein sending said instructions comprises instructing the circuit-switching switch to perform a service observation of the extension line using a CTI link.
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.
10. The method of claim 9 comprising:
recording at least the portion of the telephone call.
11. The method of claim 9 comprising:
performing live-monitoring of at least the portion of the telephone call.
12. The method of claim 9 comprising:
sending instructions over the packet-switch network to tap an extension line coupled to the circuit-switching switch; and
receiving, over the packet-switch network, audio data of telephone calls delivered over the extension line.
13. The method of claim 9 comprising:
sending instructions over the packet-switch network to tap a trunk coupled to the circuit-switching switch; and
receiving, over the packet-switch network, audio data of telephone calls delivered over the trunk.
14. The method of claim 9 comprising:
sending instructions over the packet-switch network to observe an extension line coupled to the circuit-switching switch; and
receiving, over the packet-switch network, telephone calls delivered over the extension line.
15. The method of claim 14 , wherein sending the instructions comprises dialing via the packet-switch network a code to perform a service observation of the extension line.
16. The method of claim 14 , wherein sending said instructions comprises instructing the circuit-switching switch to perform a service observation of the extension line using a CTI link.
