How do you enable stations to be built with a new range starting with the digit 7?

To enable stations with a new range starting with the digit 7, changing the dial plan analysis is the appropriate action. The dial plan analysis is responsible for defining the structure of the numbering for extensions within a telephony system. By modifying the dial plan analysis, you can specify how numbers are interpreted, including any new prefixes or patterns like those starting with 7.

Adjusting the dial plan parameters does not specify how to handle the unique pattern of a new range and may not provide the flexibility needed to accommodate the new station requirements. Adding a station range or creating a specific range for 7 would be relevant only if the dial plan already supports that prefix; hence, without modifying the analysis, those actions would not effectively enable the system to recognize and process those extension requests correctly.

Thus, to set up the system to understand and allow for these new 7-prefixed station numbers, changing the dial plan analysis is essential.
