GoIP_8 config by line
You need to set parameters for each line and the setting method is the same. The setting
parameters are as follows:
A) Telephone Number
This parameter is used to set the telephone number of the line. The telephone number is an
unique ID when the gateway serves as the callee.
B) Gateway Prefix
The gateway prefix enables the connection of calls through a particular line. It can match the
first digit only. You can set a gateway prefix for multiple lines. When you set a gateway prefix for
multiple lines, the calls that have the same gateway prefix will select the line set with this gateway
prefix. For example, the gateway prefix is 1. When the user dials 10086, the call will be connected by
the line with the gateway prefix 1. When the user dials 075588290211, the system detects whether the
line with gateway prefix 0 exists. If exists, the call will be connected. Otherwise, the call will be
released.
Note: When you set the GoIP by lines, the gateway prefix must be set. Otherwise, the call will not be connected.
