An extension is generally a 4 digit number which allows you to internally dial and connect to another caller. To simplify, a phone number is the main contact number which a customer dials to reach your organization, whereas an extension is a more focused part of your organization. The customer can reach a specific department by dialing your main number followed by an extension.
The customers don’t have to dial a different number to reach another department as it allows you to transfer a call from one extension to another. Employees can also call each other by dialing a particular extension.
