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. The default SIP protocol
port 5060 is known, but the used RTP ports can be anything between
2000 and 65353. Most SIP clients have some setting to define the RTP
port range and use port numbers above 10000 for RTP.
Therefore, it is needed to setup Port Forwarding in your router and
let the router send all the wanted ports to the V-Tap proxy server.
It might be easier to enable the DMZ Host function in your router
(when available) and let that send to the IP of the proxy server.
- The public IP address of your router (WAN IP) must be entered with
the /R option in the 'Proxy Server V-Tap IP Address' setting.
- The public IP address of your router must be entered as the
'Outbound Proxy Server' in the settings of your SIP client.
- The 'Proxy Source IP Address' in the V-Tap must be left empty, or
only a port number must be entered, when not using port 5060.
This is, because the source IP address is unknown in advance when
you are on a GSM or Wi-Fi network somewhere.
But, if the public IP address of the used SIP client is known and is
always the same, then it is better to enter that IP as the source.
Example for a router on WAN IP
V-Tap: V-Tap IP Address
Gateway Address
Proxy Server V-Tap IP Address =
Proxy Source IP Address
Proxy Destination Address
Router: Port Forwarding or DMZ Host =
Client: Outbound Proxy Server
(When the standard SIP port 5060 is used, then :6077 can be left out.)
Note that the V-Tap IP Address and the Proxy Server V-Tap IP Address
can be the same address. For a drawn scheme, see
