Description

A METHOD AND SYSTEM FOR MONITORING AND RECORDING VOICE
FROM CIRCUIT-SWITCHED SWITCHES VIA A PACKET-SWITCHED
NETWORK

BACKGROUND OF THE INVENTION
Telephone call recording and monitoring systems are increasingly being used by businesses to monitor the effectiveness of agents who receive telephone calls.
At present, the switching market is dominated by circuit-switched technologies, howeverVoIP
recording systems designed to recordVolP packets are also available.
Existing circuit-switched telephone call recording systems installed in a circuit-switched environment may operate by tapping the extensions or trunks coupled to the circuit-switched switch. Alternatively, the recording system may use the service observation feature of the switch or a dedicated recording connection to observe silently an extension.
Usually, the recording and monitoring system is installed locally at the site of the switch. A locally installed system requires expensive dedicated hardware.
Alternatively, an organization having multiple remote offices may hire dedicated expensive tie lines for storing the audio at a central location. It is not practical, however, to provide recording services by an application service provider (ASP) using dedicated expensive tie lines.

SUMMARY OF THE INVENTION
In some aspects, there is provided a method for monitoring telephone calls of agents handled by a circuit-switching switch, the method comprising: sending instructions from a recording system over a packet-switch network to the circuit-switching switch to tap an extension line or trunk coupled to the circuit-switching switch and to convert audio of at least a portion of telephone calls being transferred over said extension line or said trunk into packets of audio; and receiving over said packet-switch network at least a potion of said packets of audio.
In some aspects, there is provided a method for monitoring telephone calls of agents handled by a circuit-switching switch, the method comprising: sending instructions from a recording system over a packet-switch network to the circuit-switching switch to observe an extension line coupled to the circuit-switching switch and to convert audio of at least a portion of telephone calls being transferred over said extension line into packets of audio; and receiving over said packet-switch network at least a potion of said packets of audio.

I

In some aspects, there is provided a method for monitoring telephone calls handled by a circuit-switching switch coupled to a packet-switch network via a dedicated trunk, the method comprising: receiving for recording or live-monitoring by a recording system coupled to the packet-switch network, packets of audio of at least a portion of said telephone calls being handled by the circuit-switching switch over the packet-switch network via the dedicated trunk to enable automatic transmission of the packets of audio from said switch to the recording system.
In some aspects, there is provided a method for monitoring telephone calls of agents handled by a circuit-switching switch, the method comprising: receiving by a recording system via a packet-switch network a CTI datum or a real-time CDR datum associated with a telephone call being handled by the circuit-switching switch coupled to said packet-switch network; determining by said recording system whether said telephone call is to be recorded by determining whether said CTI datum or said real-time CDR datum meets at least one predefined monitoring condition; and if said telephone call is to be recorded or live-monitored, sending instructions from the recording system to the circuit-switching switch to capture audio associated with the telephone call; and receiving the audio of at least a portion of said telephone call via said packet-switch network for recording.
In some aspects, there is provided a recording system for monitoring and recording over a packet-switch network, telephone calls of agents handled by a circuit-switching switch, the system comprising: a recording unit coupled to the packet-switch network and able to send instructions to said circuit-switching switch, via said packet-switch network to capture audio of at least a portion of one or more telephone calls handled by said circuit-switching switch; and a management unit coupled to said recording unit and to said packet-switch network to send over said network to said circuit-switching switch commands enabling said audio to be sent to said recording unit via said packet-switch network.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by those of ordinary skill in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the present invention.

Some embodiments of the present invention are directed to remotely recording and monitoring by a single voice recording system, via a packet-switched network, telephone calls handled by circuit-switched switches. Other embodiments are directed to locally recording, via a packet-switched network, telephone calls handled by a circuit-switched switch. Non-limiting examples of a circuit-switched switch, which is coupled to a public switched telephone network (PSTN), include a private branch exchange (PBX), an automatic call distributor (ACD) a central office, and a trading floor switch.

The packet-switched network may be a local area network (LAN) or a wide area network (WAN) enabling remote recording of a single or multiple switches. Non-limiting examples of packet-switclied networks may include Internet protocol (IP) networks, ATM
networks, frame relay (FR) networks, DSL networks and ADSL networks.

For clarity, the following description sometimes uses the example voice over Internet protocol (VoIP) as a generic term for voice over packets (VoP) technologies.
However, it will be appreciated by persons skilled in the art that embodiments of the invention are equally applicable to other VoP technologies, such as for example, VoATM
and VoFR.
Various embodiments of the present invention will now be described. In some embodiments, which will be described hereinbelow with respect to Fig. 2, a circuit-switched recording and monitoring system may remotely record and/or monitor telephone calls by trunk and/or extension tapping over a packet-switched network. In other embodiments, which will be described hereinbelow with respect to Figs. 3 and 4, a circuit-switched recording and monitoring system may record and/or 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.

When the circuit-switched switch is coupled to the packet-switched network via a CTI link or a real time call detailed record (CDR) link, a selective recording based on call information is enabled. In these embodiments, the recording system may receive call information over the CTI or real time CDR link and may decide according to predefined criteria whether to record the call. Only audio from calls to be recorded are delivered over the packet-switched network In further embodiments, which will be described hereinbelow with respect to Fig.
5, a circuit-switched recording and monitoring system may record and/or monitor telephone calls over a packet-switched network from a circuit-switched switch coupled to the packet-switched network via a dedicated trunk.

In further embodiments, which will be described hereinbelow with respect to Fig.
7, a VoIP recording and monitoring system remotely or locally may record telephone calls over a packet-switched network. According to the circuit-switched switch handling the telephone call, the audio from the call may be captured by trunk and/or extension tapping over a packet-switched network or by activating the service observation feature of the circuit-switched switch either by feature code dialing or a computer telephony integration (CTI) link command. Alternatively, the audio may be delivered to the packet-switched network via a dedicated trunk coupled to the circuit-switched switch.

Reference is now made to Fig. 1, which is a block diagram illustration of an environment having a circuit-switched recording and monitoring system coupled to circuit-switched switches via a packet-switched network according to some embodiments of the present invention. In the exemplary illustration of Fig. 1, a call center environment 12, a call center environment 42, a call center environment 52, and a recording environment 14, each coupled to a packet-switched network 16, are shown. It should be understood that generally one or more call center environments might be coupled to via the packet switch network to the recording environment.

Call center environment 12 may comprise a circuit-switched switch 18 coupled to a public switched telephone network (PSTN) 20 via at least one trunk 22 and to a packet-switched network 16 via one or more VoIP switch-gateways 24. VoIP
gateway 24 may be implemented as software, hardware, or any combination thereof. Such a VoIP
gateway may be an external device coupled to the switch, such as commercially available from AudioCodes of Yehud, Israel. Alternatively, VoIP gateway may be implemented as a switch card, commercially available from Avaya of Basking Ridge, NJ, USA.

Call center environment 12 may further comprise a plurality of agent telephone stations 26, each coupled to circuit-switched switch 18 via an extension line 27. Telephone stations 26 may be either analog or digital stations.

VoIP gateway 24A may be coupled in parallel to each extension line 27. When a call is transferred from PSTN 20 via trunk 22 to circuit-switched switch 18, which routes the call to a specific telephone station 26, VoIP gateway 24A may tap the extension line 27 coupled to the specific telephone station 26, capture the audio and deliver it via packet-switched network 16 to recording environment 14.

VoIP gateway 24B may be coupled to trunk 22. When a call is transferred from PSTN 20 via trunk 22 to circuit-switched switch 18, which routes the call to one of telephone stations 26, VoIP gateway 24B may tap the trunk, capture the audio and deliver it via packet-switched network 16 to recording environment 14.

Recording environment 14 may comprise a circuit-switched voice recording and monitoring system 28 coupled to packet-switched network 16 via a VoIP
recording-gateway 30 and a network management unit 32 coupled to system 28 and to packet-switched network 16. Alternatively, system 28 may comprise only recording capabilities or live monitoring capabilities. Circuit-switched voice recording and monitoring system 28 may be any available recording and monitoring system, such as, for example, Nice Logging System, manufactured by Nice Systems Ltd. of Ra'anana, Israel.

Reference is additionally made to Fig. 2, which is a simplified flowchart illustration of a method of recording a telephone call from call center environment 12 of Fig. 1 according to some embodiments of the present invention. In one method described in Fig. 2, the audio handled by switch 18 may be captured by gateway 24B by tapping trunk 22. In this method, only audio from incoming calls received at switch 18 from via trunk 22 or outgoing calls delivered from switch 18 to PSTN 20 via trunk 22 may be captured. In another method described in Fig. 2, the audio may be captured by gateway 24A by tapping an extension line 27 coupled to a particular telephone station 26. In this method, also audio from internal calls between telephone stations 26 may be captured by gateway 24A.
According to some embodiments of the present invention, network management unit 32 may send commands via packet-circuit network 16 to VoIP gateways 24 and 30 to establish VoP sessions between gateway 30 and gateway 24 over network 16 (step 100).
These sessions may be used to deliver voice between circuit-switched switch 18 and recording system 28.

Network management unit 32 may send a command to one of gateways 24 to convert the audio of the required extension line 27 or trunk 22 to voice packets and to switch the voice packets to one of the available VoIP sessions (step 102).
Then, gateway 24 may convert the audio and may send the voice packets to gateWay 30 over packet-switched network 16 (step 104). Gateway 30 may convert the received voice packets back to circuit-switched audio (step 106). The circuit-switched audio may then be provided to circuit-switched recording system 28 for recording and/or live monitoring (step 108).

Referring back to Fig. 1, call center environment 42 having a circuit-switched switcll that enables service observation by feature code dialing will now be described.

According to some embodiments of the present invention, call center environment 42 may comprise a circuit-switched switch 44 coupled to PSTN 20 via at least one trunk 23 and to packet-switched network 16 via a VoIP switch-gateway 46.
VoIP
gateway 46 may be implemented as software, hardware, or any combination thereof.
Circuit-switched switch 44 may comprise a "service observation by code dialing" module 48. VoIP gateway 46 may activate service observation module 48 for observing the extension line 27 coupled to the specific telephone station 26 by using a code-dialing feature.

Reference is additionally made to Fig. 3, which is a simplified flowchart illustration of a method of recording a telephone call from call center environment 42 of Fig. 1 according to some embodiments of the present invention. This method enables the recording system to record audio from an incoming call, an outgoing call or an internal call delivered over any extension line 27 without having a physical connection between the VoIP gateway and the extension lines. The code-dialing feature may enable selective recording of telephone calls according to a time-schedule or other information stored in the recording system.

In the method described in Fig. 3, network management unit 32 may send commands via packet-switched network 16 to VoIP gateways 46 and 30 to establish VoIP
sessions between gateway 30 and gateway 46 over network 16 (step 300). These sessions may be used to deliver voice from circuit-switched switch 44 to recording system 28. The audio handled by switch 44 may be captured by gateway 46 by entering the service observation module.

Voice recording system 28 may activate the service observation module 48 for a desired extension line 27 by dialing the service observation code over packet-switched network 16 via VoIP gateway 46 (302). Circuit-switched switch 44 may perform the service observation on the desired extension 27 and may send the audio to VoIP
gateway 46 (304). VoIP gateway 46 may convert the audio to voice packets and may send the voice packets to gateway 30 over packet-switched network 16 (step 306). Gateway 30 may convert the received voice packets back to circuit-switched audio (step 308).
The circuit-switched audio may then be provided to circuit-switched recording system 28 for recording and/or live monitoring (step 310).

Referring back to Fig. 1, call center environment 52 having a circuit-switched switch coupled to a packet-switched network via a VoIP gateway and a CTI link enabling service observation by CTI link command will now be described.

According to some embodiments of the present invention, call center environment 52 may comprise a circuit-switched switch 54 coupled to PSTN 20 via at least one trunk 25 and to packet-switched network 16 via a VoIP switch-gateway 56. VoIP gateway 56 may be implemented as software, hardware, or any combination thereof. Circuit-switched switch 54 may be additionally coupled to packet-switched network 16 via a CTI
link 58.
Alternatively, circuit-switched switch 54 may be additionally coupled to packet-switched network 16 via a real-time CDR link.

The CTI link or real time CDR link may enable switch 54 to receive commands over packet-switched network 16. It may also enable the recording system to receive information relating to a telephone call from switch 54 for determining according to predefined criteria whether to record the specific telephone call. Non-limiting examples of such criteria include the identity of the agent, the identity of the client, and more. Only audio from calls that recording system 28 decides to record may be transferred via VoIP 56 over packet-switched network 16. The CTI link or real time CDR link may also enable selective recording of telephone calls according to a time-schedule or other information not received from the circuit-switched switch.

Circuit-switched switch 54 may comprise a service observation by CTI link command dialing module 60. The service observation module for the specific extension line may be activated by a CTI link command or a real time CDR command sent over packet-switched network 16.

Reference is additionally made to Fig. 4, which is a simplified flowchart illustration of a method of recording a telephone call from call center environment 52 of Fig. 1 according to some embodiments of the present invention. This method enables the recording system to record audio delivered over any extension line 27 from an incoming call, an outgoing call or an internal call without having a physical connection between the VoIP gateway and the extension lines.

In the method described in Fig. 4, network management unit 32 may send commands via packet-circuit network 16 to VoIP gateways 56 and 30 to establish VoIP
sessions between gateway 30 and gateway 56 over network 16 (step 400). These sessions may be used to deliver voice from circuit-switched switch 54 to recording system 28.

Voice recording system 28 may activate the service observation module 60 for observing a desired extension line 27 by sending a CTI command over packet-switched network 16 via CTI link 58 (402). Circuit-switched switch 54 may perform the service observation on the desired extension 27 and may send the audio to VoIP gateway 56 (404).
VoIP gateway 56 may convert the audio to voice packets and may send the voice packets to, gateway 30 over packet-switched network 16 (step 406). Gateway 30 may convert the received voice packets back to circuit-switched audio (step 408). The circuit-switched audio may be then provided to circuit-switched recording system 28 for recording and/or live monitoring (step 410).

Reference is now to Fig. 5, which is a block diagram illustration of an environment having a circuit-switched recording system coupled to a circuit-switched switch via a packet-switched network according to some embodiments of the present invention. In the exemplary illustration of Fig. 5, a call center environment 62 and a recording environment 14 both coupled to packet-switched network 16, are shown. It should be understood that generally one or more call center environments might be coupled to via the packet switch network to the recording environment.

Call center environment 62 may comprise a circuit-switched switch 64 coupled to PSTN 20 via at least one trunk 63 and to packet-switched network 16 via a dedicated trunk 68 and a VoIP switch-gateway 66. VoIP gateway 66 may be implemented as software, hardware, or any combination thereof. Circuit-switched switch 64 may comprise a "dedicated trunk" module 70 implemented in software, hardware or a combination thereof enabling audio from trunk 23 and/or extension lines 27 to be delivered automatically to dedicated trunk 68. Dedicated trunk 68 may deliver the audio from trunk 23 and/or extensions 27 over packet-switched network to recording system 28 on a regular basis without receiving specific commands from the recording system 28. Such dedicated trunks 68 are suitable, for example, for a trading floor switch.

Reference is additionally made to Fig. 6, whicli - is a simplified flowchart illustration of a method of recording a telephone call from call center environment 62 of Fig. 5 according to some embodiments of the present invention. This method enables the recording system to record audio from an incoming call, an outgoing call or an internal call witliout sending specific commands to VoIP gateway 66.

In the method described in Fig. 6, network management unit 32 may send commands via packet-circuit network 16 to VoIP gateways 66 to establish VoP
sessions between gateway 30 and gateway 66 over network 16 (step 600). These sessions may be used to deliver voice between circuit-switched switch 64 and recording system 28.

Audio from trunk 63 and/or extension lines 27 may be delivered to dedicated trunk 68 (step 602). Then, gateway 66 may convert the audio and may send the voice packets to gateway 30 over packet-switched network 16 (step 604). Gateway 30 may convert the received voice packets back to circuit-switched audio (step 606).
The circuit-switched audio may then be provided to circuit-switched recording system 28 for recording and/or live monitoring (step 608).

Reference is now made to Fig. 7, which is a block diagram illustration of an environment having a VoIIP recording and monitoring system coupled to circuit-switched switches via a packet-switched network according to some embodiments of the present invention. In the exemplary illustration of Fig. 7, call center environment 12, call center environment 42, call center environment 52, and a VoIP recording environment 64, each coupled to packet-switched network 16, are shown. It should be understood that generally one or more call center environments might be coupled via the packet switch network to the recording environment, including call center environment 62. In particular, VoIP
recording may enable local selective recording and live-monitoring of a single circuit-switched switch without the need for proprietary hardware, such as tnmk and extension interface boards, and without the need for a direct physical connection to each extension line.

VoIP recording environment 74 may comprise a VoIP recording and monitoring systen176 coupled directly to packet-switched network 16. VoIP recording system 76 may be able to receive and record voice packets thus eliminating the need for a VoIP gateway.

Network management unit 32 may send commands either directly or via packet-circuit network 16 to VoIP recording system 76 and via packet-circuit network 16 to one of VoIP
switch-gateways 24, 46, 56, and 66 to establish VoIP sessions over network 16.
These sessions may be used to deliver voice from one of circuit-switched switches 18, 44, 54 and 64 to VoIP recording system 76.

VoIP recording system 76 may be any available VoIP recording system, such as, for example, Nice VoIP Logging System, manufactured by Nice Systems Ltd. of Ra'anana, Israel. According to these embodiments, VoIP sessions may be established between VoIP
one of switch-gateways 24, 46, 66, 56, and VoIP recording system 76. The VoIP

switch-gateway may convert the circuit-switched audio into Voice packets. The voice packets may then be delivered over packet-switched network 16 to VoIP
recording system 76 for recording.

While certain features of the invention have been illustrated and described herein, many modifications, substitutions, changes, and equivalents will now occur to those of ordinary skill in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
