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