This parameter is used for registration backup. When a backup registration server exists in the
user’s system, the user can enable this parameter. When the backup server is enabled, the gateway
will automatically log into the backup server in case of the failure of the main server.
3.5.2.4 Trunk Gateway Mode
The trunk gateway is used to connect the VoIP network with the GSM network and convert the
related protocols, so that users served by the two networks can call each other.
A) SIP Trunk Gateway1
It is the IP address of the server connected to the GoIP gateway. When the registration timeout is
0, the GoIP is connected to the SIP server. If the registration timeout is not 0, the GoIP logs into the
SIP Trunk Gateway1 server through setting the telephone number, authentication ID and password.
B) SIP Trunk Gateway2
It is the IP address of the terminal connected to the GoIP gateway, which can be an IP segment,
such as 192.168.2.X. This means that all terminals connected over 192.168.2 segment can log into the
GoIP and land through the direct connection between the GoIP and the GSM network.
