Establishing a Call Between Two Gateways

After you've installed and set up the VCX V7111, you can ensure that it functions as
expected by establishing a call between it and another gateway. This section exemplifies
how to configure two 8FXS SIP gateways in order to establish a call. After configuration, you
can make calls between telephones connected to a single 8FXS gateway or between the two
8FXS gateways.
In the following example, the IP address of the first gateway is 10.2.37.10 and its endpoint
numbers are 101 to 108. The IP address of the second gateway is 10.2.37.20 and its
endpoint numbers are 201 to 208.
In this example, a SIP Proxy is not used. Call routing is performed using the internal 'Tel to
IP Routing' table.
To configure the two gateways, follow these steps:
1
Configure the following settings on the first 8FXS gateway (10.2.37.10):
In the 'Endpoint Phone Numbers' screen, assign the phone numbers 101 to 108 for the
gateway's endpoints.
2 Configure the following settings on the second 8FXS gateway (10.2.37.20):
In the 'Endpoint Phone Numbers' screen, assign the phone numbers 201 to 208 for the
gateway's endpoints.
3
Configure the following settings for both gateways:
In the 'Tel To IP Routing' screen, in the first row, enter 10 in the 'Destination Phone
Prefix' field and enter the IP address of the first gateway (10.2.37.10) in the field 'IP
Address'. In the second row, enter 20 and the IP address of the second gateway
(10.2.37.20) respectively.
These settings enable the routing (from both gateways) of outgoing Tel IP calls that
start with 10 to the first gateway and calls that start with 20 to the second gateway.
