CHECKLIST FOR TUNNEL CONNECTION
A connection between V-Tap and PC software (or Apresa) is needed to get the recorded data automatically
into a user accessible database. The following checklist can be used to setup this Tunnel connection:
1) Install the Hardware and be sure that the phone’s VoIP data passes the V-Tap VoIP.
2) Install the V-Archive software on a PC and enable V-Tap connections (see page 3).
3) Open the Settings page of the V-Tap in a browser by entering http://vtapXXXX.local
XXXX are the last 4 digits of the MAC address, found on the bottom of the unit (see page 2).
Note: It may take some time after first connect before this local name is known to the network.
4) On that page, the PC’s IP address must be entered as the “Tunnel Server Address”.
5) The PC’s firewall must be open for TCP port 2016,the default “Tunnel Destination Port”.
6) The Tunnel connection to the PC is stable when the GREEN LED is steady, not blinking!
Also, the V-Tap must be shown with its MAC address in the status line of V-Archive.
7) For first tests, better turn off “Tunnel Data Encryption”. Otherwise, be sure that the Encryption
password is the same for both V-Tap and V-Archive.
8) The V-Tap stores only data that passes the “Tunnel TCP/SIP Port Filter”. In case of an unknown port
or for test, this filter can be set to zero to store all network traffic.
9) When data is stored by the V-Tap during a call, the BLUE LED blinks fast.
10) To see if the PC receives something from the V-Tap, it is possible to make a network trace for test
purposes. In V-Archive, go to menu Actions and select ‘Network trace’, press Start, make a call,
press Stop and then Save. From the zip file 'tunneltrace.pcap' can be analyzed with Wireshark.
11) The SD card in the V-Tap should contain “.TUN” files when data is captured.
The SD card can be read by the V-Archive software in menu File and ‘Import from V-Tap’.
12) When the V-Tap is connected to a trunk, then it sees all calls that are passing. The V-Tap cannot
filter those calls on phone number. There is no black- or white-list function, only an IP filter.
