Introduction
The V-Tap ISDN BRI is a hardware and software solution for the
recording of telephone calls. The supplied hardware unit can record the
audio from an ISDN-2 BRI line. 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 Call Recorder VoIP
software (running on a Windows PC). The external Apresa recorder or
CR-VoIP software can both interpret the Tunnel-format and make
playable audio files from it, together with the original date, time and
call number information (meta data).
The use of an SD card is mandatory and must be FAT32 formatted. The
recorded data is stored in WAV file format on the card. Depending on
whether a Tunnel has been defined or not, the files are sent over the
network or can be read later by the CR-VoIP software.
Note that the V-Tap ISDN BRI does not produce WAV files or store any
data on the SD card, without a Channel License for Apresa or PC.
The V-Tap ISDN BRI can operate completely stand alone and when the
capacity of the SD card is big enough, it can store data for months or
even years.
Connection to the V-Tap BRI is made with a network cable or by using
Wi-Fi, when available. The web interface can be accessed by using a
browser. The LAN cable can be connected to any of the two Ethernet
ports. Both ports (100 Mbps) are equal and part of a build-in switch.
The V-Tap ISDN BRI is a member of a family of compatible products that
can be used to create all sorts of Call Recording solutions. There are
V-Taps for VoIP, Analog and ISDN telephony, there is an App for mobile
recording and all these products communicate with the Apresa
Corporate recording solution or Apresa cloud-based recording.
NOTE 1: The V-Tap ISDN BRI needs to be powered through USB and a
FAT32 formatted SD card must be inserted.
NOTE 2: The V-Tap ISDN BRI needs at least 1 Channel License for Apresa
or PC, else no calls are stored on the SD card.
