Understand Your Dial Plans

A dial plan defines a pattern of digits that users can dial to make calls inside or outside your business. Users within the business can call each other by using short extension numbers, as defined by their internal dial plan. Users can call external numbers based on an external dial plan that follows well-established practices for a region. For example, if your users are located in North America, their external dial plan is automatically set by the North American Numbering Plan.

Your Virtual Office service comes with the default dial plan setup based on the country of your site. For example, a site located in the United States is set up with the North American Numbering Plan (NANP), which defines (3-digit area code + 7-digit phone number) when dialing within the country, and (011 + destination country code + phone number) when dialing internationally.

Users within the same business have the convenience of using short extension numbers to dial each other, regardless of where in the world they are. Short extension numbers are defined by the internal dial plan. In addition to the internal dial plan, customers can set external dial plans for the entire site or for an individual user. External dial plans define the dialed digit pattern used in specific regions, specify how to interpret phone number sequences entered by a user, and convert the sequences to normal outbound strings. For example, the North American Numbering Plan (NANP) defines a common dial pattern used by telephone networks within North America.

Using extension numbers, you can click or tap a contact from the contact directory and call your colleagues in the same office, in another city, or in another country.

Features

Note: Do not assign extension numbers to your phone service that conflict with emergency numbers, or frequently used public numbers in a specific region such as: 911 and 411 in North America, and 101 and 102 in Europe.

Note: If you must define site codes, keep them the same length across all your sites.
