The Octo and Quarto Call Recorders automatically capture and archive all telephone and radio communications. These recordings encompass entire conversations alongside vital details like external phone numbers, precise timestamps, and call durations. With the capacity to store up to 20,700 hours of calls, retrieval and playback can be effortlessly performed via the recorder’s interface or network access. A built-in CD recorder also guarantees secure backups of all recordings on compact discs, making them compatible with any standard PC.

Our product line features two distinct models:

  • Model 010.01750: The Call Recorder Quarto 19 Inch (with 4 active recording channels)
  • Model 010.01760: The Call Recorder Octo 19 Inch (offering 8 active recording channels)

An exceptional feature of these recorders is the ability to configure each channel independently. This versatility makes the Call Recorder Octo and Quarto perfect for versatile source recording solutions. For example, a single Quarto 4-channel unit can simultaneously record two telephone lines, a transceiver, and a microphone or configure them to work as a multichannel answering machine. Both the Octo and Quarto can be configured to connect before the PBX or between the PBX and the phones.
