If your organization uses three digit extensions, there are some numbers that can’t be used because they are reserved for specific tasks (i.e. emergency calls, directory assistance, etc.). Below is a list of these extensions and their designated function.

Note: You can reduce or increase your extension length. If changes are made, the system will validate the new size and display any duplicate or invalid extensions.
