When installed on a Debian Linux server, the Apresa Forwarder can forward network traffic to Call Recorder Apresa. For example, this is a way to record calls from a 3CX PBX running on the Debian server. The Apresa Forwarder sends the data to the Apresa call recorder, which records and stores the VoIP calls.

When using a 3CX PBX, the Apresa Forwarder can have access to call details that wouldn’t be available when using the port-mirroring recording method. The license requirements are exactly the same. When using the Apresa Forwarder, you’ll need one Apresa VoIP license per (simultaneously) recorded call.
