PSTN usage records are associated with routes and voice policies to provide a way to control which users are allowed to use specific routes. Voice policies are applied to users, containing a list of PSTN usages. If a user dials a number that matches a route with one of those PSTN usages, the call is placed. If not, the user is unable to make the call.
To create a new PSTN usage record, follow these steps:
1. On the Edit Voice Policy screen, click the New button in the Associated PSTN Usages section.
2. Enter a Name for the PSTN usage.
3. Click the Select button in the Associated Routes section to associate the usage with an existing route. Alternatively, click New to create a new route for the usage.
4. Select a route and click OK.
5. Click OK to save the PSTN usage record.
