Create, manage, and interpret dial plans
Dial plans are sets of rules that can convert partial dial pad entries into a standard (E.164) phone number format. E.164 is the international public telecommunication numbering plan, or international standard, that is used globally and ensures every number worldwide is unique.
We want to use a dial plan to make our users' dialing experiences as simple as possible while still utilizing full E.164 format numbers. For example, when users dial 700 from within your organization, it could direct them to the help desk. Another common example is letting users dial within the organization just by using an extension (the last three or four digits of assigned numbers). You could pair this with a dial plan setting that requires a 9 to be dialed before users can dial an external number so it doesn't attempt to interpret a full, external number as an extension.
Dial plans can be configured with the following settings:
