    V-Archive software for the PC can, just as the Apresa, receive Tunnel data from the V-Tap VoIP, convert this data into audio files and store the files into its own database. The V-Archive software can also receive multiple data streams from different V-Tap units simultaneously.

  • Page 11: Web Interface And Settings

    3 Web interface and Settings The first step to access the web interface of the V-Tap VoIP is to connect a network cable to any of the 4 LAN ports on the unit. The other side of the cable can be connected to a LAN switch or directly to a PC.

  • Page 12: Web Interface

    By pressing the Save & Logout button on the Settings page, the settings are sent to the V-Tap unit. Any ongoing recording is stopped, the file on SD card is closed, and after a few seconds the new settings are activated.

  • Page 19 .TC<sec> = Tunnel Connect Timeout (default 22 seconds) This timeout is used when the V-Tap VoIP tries to connect to the Tunnel server. The default 22 seconds is enough to send 4 requests. If no reply comes from the remote side within the timeout, the V-Tap starts trying again after a few seconds with a new source port number (see above).
  • Page 20 VoIP calls. Disabling this filter will increase the amount of stored redundant data a lot, when the V-Tap is connected to a PC LAN or trunk. .LX<size> = Maximum Data Size in packets (default 1024) This sets the maximum length of the data portion inside all communicated packets on the network for Tunnel, FTP and Web.

  • Page 21: Proxy Settings (V-Tap Voip-2/3 Only)

    Proxy mode is only available on the V-Tap VoIP-2/3 with a Proxy license. The V-Tap VoIP-2 or VoIP-3 can act as one or more proxy servers for VoIP devices that are using the SIP protocol, like a SIP telephone or PBX.
  • Page 22 Proxy Destination Address This is the IP address or hostname of your VoIP provider or other VoIP PBX. The V-Tap needs to know this address, so it can forward all packets coming from the VoIP device(s) to this provider. A protocol port number can be added with the :<port> notation behind the address.
  • Page 23 Proxy Destination Address = sip.voip-provider.com The above means that 5 devices can use the V-Tap as proxy and can therefore be recorded at the same time. For this to work, at least 5 Proxy licenses must be available inside the V-Tap.
  • Page 24 Proxy Public Access, using a direct WAN IP address The V-Tap can be given a public (WAN) IP address itself, and therefore becomes directly accessible from the internet by any SIP client on your mobile telephone. Note, that the web settings page of the V-Tap can also become available on the internet in this case (1 example).
  • Page 25 Proxy Public Access, using a Router and Port Forwarding When the V-Tap is connected to your LAN and must record all calls from a SIP client that is running on your mobile telephone, for example, then these points must be met: Your router must be open for the SIP protocol port AND for the used RTP ports that carry the audio of the calls.
  • Page 26 Both message and beep can be activated separately or work simultaneously. The audio of the beep is also stored inside the V-Tap in a file called “NBEEP.WAV” and also in the format G.711-Alaw, 8KHz, Mono. To enable the beep, add behind the Proxy Notify & Record Options: /B<sec>...
  • Page 27 The G.722 and G.729 codecs are disabled by the V-Tap in the SIP protocol when a message is used, but the safest way of operation is to put the PCMA codec (G.711-Alaw) on top of the codec- list in your VoIP system.
  • Page 28 Proxy DTMF Start/Stop Options In Proxy mode, the V-Tap VoIP-2 or VoIP-3 can detect DTMF codes in the RTP stream (RFC 2833 / 4733) and inside SIP INFO messages. To enable DTMF detection, a numeric value must be entered: +1 : Enable DTMF detection for remote side.

  • Page 30: Ntp And Date+Time Settings

    NTP and Date+Time settings NTP (Network Time Protocol) can be used to synchronize the internal clock. The V-Tap VoIP also has an internal battery to keep the clock running when power fails, but this is not as accurate as the clock on an NTP server.

  • Page 34: Licenses & Versions

    For example, when two VoIP calls are busy at the same time and the V-Tap has only one license, then the second call will be discarded by the Tunnel server and cannot be recovered anymore later. For the V-Tap VoIP-2 and VoIP-3 there also exists a value for the Proxy-mode licenses.

  • Page 35: Led's

    LED’s can tell you if things are going wrong or right. The Blue LED may always blink a little when the network is connected, meaning that data is received by the V-Tap VoIP. The status of the V-Tap must be read from the Red, Green and Amber LED’s.

  • Page 40: Copy Settings From Sd Card

    5.5 Copy Settings from SD card The V-Tap automatically copies the settings files to the root of the SD card, directly after insertion (only if they do not exist already). The file CFG.VTV from the SD card can be edited with a text editor on the PC and then be copied back to internal memory.

  • Page 41: Firmware Update

    When the system is accessible through FTP, the firmware can be updated with the PC tool ‘vcUpdater’. This tool can be found on the Vidicode website in the menu Service and Support > Firmware. Another way to update is by using an SD card as follows: - The manufacturer must provide the necessary files first.

  • Page 42: Sd Card Usage

    6 SD card usage Without an SD card inserted, the V-Tap VoIP will steam the sniffed data live to the Tunnel server (Apresa or V-Archive software). The SD card is used to store the recorded VoIP data. The system writes the data to files in the Tunnel format, which is the same as the format sent to a Tunnel server.

  • Page 43: Special Sd Card Settings

    In the case that only one VoIP phone is connected, the files on SD card will then contain complete calls. With more phones/calls active at the same time, the files can also contain multiple calls. V-Tap VoIP Manual EN v3.23 Aug 2021 © 2017-2021 Vidicode...
  • Page 44 Sending files via the Tunnel can be scheduled into a timeframe. If lots of data has been received by the V-Tap and therefor also lots of data must be send to the Tunnel server, it might be useful to delay the sending to save bandwidth on the network.
  • Page 45 .CA = Store files on the card in PCAP format Enabling this option sets the V-Tap unit in a completely different mode. The format of the stored packets in the files on the SD card changes to the PCAP format. The files on the card are given the extension .CAP and are directly readable by PC tools like Wireshark.
