Gateway A: Dial Plan Setup
FXS Ports to Analog Phones - Gateway A has two phones on the FXS ports. Telephone number 203 on Port 2 and 204 on Port 3. These numbers are part of the default dial plan and do not have to be entered. We can skip the local Dial Plan setup including Telephone Address, hunt group and destination for phones 203 and 204.
How to Enter the Dial Plan
The Dial plan consists of three tables that include the Telephone Table, Hunt Group (eg. Customer Service may have multiple phones that the GW must search through for an open line), and Destination Table (Both Local and Remote). The dial plan has to be entered into all Gateways so that the local gateway knows how to process calls, sending them to its local ports or to remote gateways for further processing.
