2.1 Methods to Number Dialing

Dial mobile phone or extension number
Dial the number directly and wait for 3 seconds (Default "No dial timeout");
Dial the number directly and press #.

2.2 Direct IP Calls

The VGW-x20FS series gateway allows users to directly call through IP address. Under this
circumstance, the user only needs an analog phone which is connected to an FXS port of the gateway,
and calls can be established without registration.
Calls can be established through IP address as long as one of the following conditions is met.
Both the VGW-x20FS series and other VoIP device have public IP addresses;
The VGW-x20FS series and other VoIP device use private IP addresses of the same LAN;
The VGW-x20FS series and other VoIP device can be connected through a router and use public or
private IP addresses (with necessary port forwarding or DMZ).
Operation Process：
Step 1: Pick up the analog phone and then dial "*47";
Step 2: Enter the target IP address.
No dial tone will be played between step 1 and step 2.
Example:
Assume that the target IP address is 192.168.0.1, user need to dial *47 and then 192*168*0*1. After
that, press the "#" key or wait for 3 seconds. Then signaling interaction is completed and ringing can
be heard.
You cannot make direct IP calls between FXS0 and FXS1 of the same VGW-x20FS
series since they are using the same IP addresses. Call through IP address is only
routed to the default destination port 5060 .
