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 calls are stored onto an SD card in WAV files, and therefore the V-Tap ISDN BRI or PRI can operate stand-alone. The content of the SD card can be 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.
