Basic principles of CyberTech Recording

A CyberTech Recording system consists of

1. Input channels- mix of analog, digital, trunk, VoIP

2. Hardware- Commercial-off-the-shelf (COTS)

3. Software- completely web-based user interface

1. Different input methods can be combined

Our differences

• 256 bits AES Audio Encryption (key management)• MD5 Fingerprint ( No audio manipulation)• SOE Compatible

(Standard Operating Environment)• Uses standardized hardware (of the shelf)• Runs as ‘Service’ (No Application)• Adheres Sarbanes Oxley regulations• Supports multi PBX’s and channels in one chassis• One and easy user interface• Low install cost• Low maintenance cost

VoIP recording – standard features

• No line cards

• Passive or active• License based

• G.711 or with G.729 audio compression• Recording MAC-based or IP-based

• Different VoIP protocols within the same recorder system

• Concurrent licensing possibility

Cisco VoIP recording methods

1. Passive VoIP recording2. Gateway recording

3. Active VoIP recording Planned for Q4/2008

30-Mar-09 – slide 9

1. Cisco Passive VoIP recording

• Using SPAN port of the network switches• IP phones put in a voice VLAN• Call data is also tapped from SPAN port• No CTI required from Cisco• Concurrent licenses possible• Cannot be used for encrypted VoIP• Recording of G711 or G729 (optional)

SCCP protocols• Approved by Cisco

2. Cisco Gateway Recording

• Extension based recording

• Less complex spanning– Span/Mirror Call Manager and Gateways

• Less complex configuration– IP address of Call Manager and Gateways– List of extension to be recorded

• No CTI required from Cisco

• Already deployed with large global financial institutions

Passive SPAN port versus Active recording

• Pro’s SPAN port versus Active recording– Lower cost (no CTI)– Low recorder complexity– Less PBX configuration dependence

• Cons SPAN port versus Active recording– No support for encrypted VoIP– SPAN functionality required in IPT network– SPAN configuration and compliance– Spanning Gateway strips out IP and MAC addresses so

remote IP extensions can be difficult to tag data to and record – Active recording gets around this

3. Cisco Active IP recording

• JTAPI connection is used for the conference/silent monitor facility

• Calls to be recorded are ‘conferenced’ to a SIP trunk which is actively terminated at the recorder

• Call details are read from the JTAPI interface

• The number of concurrent recordings available is depending on the Cisco conferencing/silent monitor facility. These require audio mixing facilities within the Cisco IPCC.

Planned for Q4/2008

Cisco Active IP overview

• Concept– Conference mixing resources in 79x1 phones– SIP call established with recorder– JTAPI target monitoring to trigger recording

• Requirements Cisco– IPCC 8.0, CM 6.x– 3rd generation IP phones– SIP trunk on IPCC – JTAPI target monitoring licenses

• Requirements CyberTech– CTI Server JTAPI including target licenses– SIP Recording channel per target
