Example of Connecting Two 8FXS Devices
This example applies to H.323 and SIP. Figure 20 on page 40 shows an example of two
VCX V7111 8FXS
devices’ internal routing tables. Phone 2001 is connected to the first
channel of gateway 10.2.222.108, and phone 2101 is connected to the first channel of
gateway 10.2.222.107.
To make a call between two gateways, lift the receiver of phone 2001; you hear a dial tone
and the first channel’s LED lights up. Dial 2101; after dialing the last digit, the data LED
begins blinking (indicating traffic) and phone 2101 rings.
The prefixes you choose in the ‘Tel to IP Routing’ table
must differentiate
the
media gateways from each other to ensure correct routing. In the example, using
the first digit (2) doesn’t differentiate the devices, thus 2 digits of the phone number
are used.
To enable
phones connected to the same
VCX V7111 to communicate with
each
other,
define in the internal routing table the IP address and corresponding phone
numbers of the device itself (applicable only to H.323 devices).
