3.4.4 Example of Connecting Two MP-108 Devices
This example applies to H.323 and SIP. Figure 3-6 below shows an example of two MP-108/FXS
devices’ internal routing tables. The 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.
Note 1: The prefixes you choose in the ‘Tel to IP Routing’ table must differentiate the
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.
Note 2: To enable phones connected to the same MP-1xx 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).
