What are extension numbers and how do they work?
Extension numbers are a series of digits that are used to connect callers to specific individuals or departments within an organization. They are typically used in conjunction with a main phone number, and allow callers to dial a specific code to reach the desired party. For example, a company may have a main phone number of 555-1234, and extension numbers such as 101, 102, and 103 to connect callers to different employees or departments.
The way extension numbers work is that when a caller dials the main phone number, they are typically greeted by an automated attendant or a receptionist who asks them to enter the extension number of the person they wish to reach. The caller then enters the extension number using their phone’s keypad, and the call is routed to the corresponding phone or voicemail box. Extension numbers can be assigned to specific individuals, departments, or even specific functions, such as a sales or customer service department. They provide a convenient and efficient way for organizations to manage incoming calls and ensure that callers are directed to the right person or department.
How are extension numbers assigned and managed?
Extension numbers are typically assigned and managed by an organization’s phone system administrator or IT department.
