Proxy Settings (V-Tap Voip-2/3 Only) - Vidicode V-Tap Manual

3.3.4
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.
When setup right, all calls will pass the V-Tap and are recorded.
The big advantage of using the Proxy mode is, that a notification
message can be played, and that the user can start and stop recording
by pressing a key on his telephone (record-on-demand with DTMF).
The V-Tap forwards the SIP and RTP packets from the source VoIP device
(client) to the destination VoIP provider and vice versa. In this way the
SIP registration is still handled by the VoIP device itself and the V-Tap
does not need to know the user's account information.
All other sniffing rules still apply when Proxy mode is active. So, the "IP
Address Filter" and "SIP/RTP Port Filters" are still used to decide whether
a packet must be stored onto the SD card or not.
One or more VoIP devices can be recorded by using the V-Tap as its
proxy server; see Single- and Multi-Proxy mode further on.
There are three main settings involved to setup Proxy mode:
Proxy Server V-Tap IP Address
This is the IP address of the V-Tap as proxy server and must be the
same as the proxy address that you have entered in your VoIP device
(sometimes also called Outbound Proxy).
In case that more devices must be recorded, each using its own
proxy, an IP range can be entered with a hyphen or minus sign
between two IP addresses. See Multi-Proxy mode further on.
The entered IP for the proxy server is normally a private address that
is part of the local network. However, it is also possible to enter a
public address (WAN IP), directly accessible from the internet.
In some situations, it might be needed to use a different gateway to
access the proxy destination. Another gateway IP address can be
entered by adding the option /Gx.x.x.x behind the proxy server.
A special case is, when the V-Tap proxy server is on a local network,
but the SIP client (proxy source) is on the internet somewhere. Then,
the public IP address of your router must be entered by adding the
option /Rx.x.x.x behind. See Proxy Public Access further on.
