Checklist for Tunnel connection
A connection between V-Tap and Apresa or PC software 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 VoIP data passes the V-Tap.
2)
Install the Apresa or PC
Software
and enable V-Tap connections.
3)
Assign an
IP address
to the V-Tap and open the
Settings page
.
4)
The “
Tunnel Server Address
”
must be filled in with the IP address or
name of the Apresa recorder or the PC.
5)
Any
firewall
must be setup to let pass TCP port 2016, the default
“
Tunnel Destination Port
”.
6)
The Tunnel connection to the Apresa or PC software is stable when the
GREEN LED is steady
, not blinking!
7)
For first tests,
better turn off “Tunnel Data Encryption”. Otherw
ise, be
sure that the Encryption password is the same for both V-Tap and
Tunnel server.
8)
The V-Tap stores only
VoIP data that passes the “Tunnel TCP Port Filter”.
In case of an unknown VoIP port or for test, this filter can be set to zero
to store all network traffic.
9)
When data is stored during a call then the
BLUE LED
blinks.
10)
To see if the Apresa or PC receives something from the V-Tap, it is
possible to make a network trace for test purposes.
On the PC go to menu Action and select ‘Network trace’. The
'tunneltrace.pcap' file can be read afterwards with Wireshark.
11)
The SD card in the V-
Tap should contain “.TUN” files.
The SD card can be read by the PC software in menu File and ‘Import
from V-
Tap’.
