Introduction
The V-Tap ISDN PRI is a hardware and software solution for the
recording of telephone calls. The supplied hardware unit can record the
audio from an ISDN-30 line with 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 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 (G.711 A-Law).
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 PRI does not produce WAV files or store any
data on the SD card without Recording Channel Licenses.
The V-Tap ISDN PRI 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 PRI is made with a network cable or by using
Wi-Fi, when available. The web interface can be accessed by using a
normal browser. The LAN cable must be connected to the Ethernet port,
which is 100 Mbps Full Duplex.
The V-Tap ISDN PRI 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 PRI needs to be powered through USB and a
FAT32 formatted SD card must be inserted.
NOTE 2: The V-Tap ISDN PRI needs at least one Recording Channel
License, else no calls are stored on the SD card.
