  • In a multi-site network, branches where few calls have to be recorded, the deployment of a recorder does not require a dedicated recording server for each remote site.
  • Theoretically, this recorder eliminates the complexity of the switching infrastructure compared to the passive recording method, because the RTP streams are sent directly to the recording server automatically.
  • Can be easily scaled by adding new recorders to the system if more capacity is required.
  • Does not require extra DSP resources from the network compared to the active (conference-based) method.
  • Recording tone can be generated by the phone.
  • Encrypted calls can be recorded since CUCM 8.0

The Verba passive, network spanning / traffic monitoring-based recording engine technology supports all Cisco phones, however, the Verba central recording technology needs cooperation from software built into the Cisco phones to deliver the recording function. Not all Cisco phones support this recording mode, one requirement is the build-in-bridge technology in the phone.
