Digital Call Recorder

Digital lines cannot be recorded unless the call recording system can capture and decode the proprietary digital signalling, which some modern systems can. Sometimes a method is supplied with a digital PBX that can process the proprietary signal (usually a conversion box) before being channeled to a computer for recording. Alternatively a hardware adapter can be used on a telephone handset as the digital signal is converted at that point to analogue.

VoIP Recording is usually restricted to streaming media recorders or software developed by the softphone or IP PBX creator. There are also solutions which use packet capture technology to passively record VoIP phone calls on the LAN.
