3.4.4 Example of Connecting Two MP-118 Devices 
This example applies to H.323 and SIP. Figure  3-6 below shows an example of two MP-118/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’; a dial tone is heard and 
the first Channel Status LED lights up. Dial 2101; after dialing the last digit 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 MediaPack to communicate with each 
other,  define in the internal routing table  the IP address and corresponding 
phone numbers of the device itself.
