Crystal Gears VoIP Recording

Crystal Gears supports recording of almost all VoIP telephones. CG VoIP installation consists of installing the CG software application on your computer and connecting the interface module (CG VoIP Box) to the network switch, phone base, and PC NIC card, or for recording IP softphones and some VoIP hardphones, like Cisco 7970, 7941 and Yealink SIP phones that support the "Span to PC port" feature, no interface model is needed.

Crystal Gears VoIP Box

The CG VoIP Box acts as a convergence point of a network, allowing the transfer of data packet copies. CG VoIP Box duplicates the data packets received via one port and makes it available to all ports, allowing data sharing between all devices connected to the box. CG decodes the incoming data packets to reassemble the original conversations and record them. Since Crystal Gears works with the most popular IP platforms, it decodes a variety of VoIP protocols and extracts phone on/off hook events which will be translated into searchable call recording start/stop trigger messages, as well as call information such as:

  • Caller ID
  • Called ID
  • Call direction
  • Call parking
  • Call hold
