Your telephone recordings stored on an SD card
The V-Tap ISDN BRI or PRI is a hardware and software solution for the recording of telephone calls. The supplied hardware unit can record the audio from an ISDN 2 or 30 line with S0 or E1 interface. The recorded data is stored digitally onto an SD card and is sent optionally over the network, in which case the data is wrapped into a special Tunnel-format that can be received by the Call Recorder Apresa (running on Linux) or by the V-Archive software (running on a Windows PC). The external Apresa recorder or V-Archive software can both interpret the Tunnel-format and make playable audio files from it, together with the original date, time and call number information.
