A phone extension is an additional telephone number that is assigned to a specific user or department within a company. Phone extensions allow employees to be reached directly without having to go through a receptionist or operator. This can save time and improve communication efficiency.
Phone extensions are typically used in businesses with multiple employees. They can also be used in homes with multiple phone lines. Phone extensions can be assigned to individual employees, departments, or even specific projects. This allows for easy call routing and can help to improve customer service.
