How to record PBX extensions with a voice logger

Connecting a voice logger to the extension lines that come from a PBX offers the most recording data and options and should always be considered as your first option. Unlike recording from the trunk or handset, attaching a voice logger to your extension lines requires that your voice logger be compatible with your PBX. This is because the PBX literally communicates its information to the voice logger. A list of compatible PBXs and phones currently usable with all Versadial voice loggers. Most Major PBXs from manufacturers such as Avaya, Cisco, NEC, Nortel and Panasonic are supported. The lines between the Versadial voice logger and where you are tapping your extension lines should generally be no longer than 30 feet to insure that the signal quality of the recordings stays strong. One of the advantages of recording from the extension is that the voice logging software will gather call data directly from the PBX and append it to each recording. This information usually includes the extension making the call, the caller ID, or if the call was outbound or inbound.

The pros

  • Extension to extension calls inside your company can be recorded.
  • Detailed data from the PBX is integrated into each recording.
  • You can select which extensions to record and which not to record.
  • Recordings are saved in folders by the extension they came from.

The cons

  • Usually more lines to tap. This usually means longer installation times.
  • Usually more expensive than trunk side recording because of greater hardware needs.
  • Not all PBXs are supported.
