How do extensions work?
Extensions work both internally and externally. Internal working is between the companies itself. Internal working can also mean different offices in the different parts of the country of the same company and external working involves all the interested outsiders- customers, suppliers and investors wanting to communicate with internal working members of the company. Let us understand both.
Internal Extensions: Communication in-between the same departments and different departments happen within the company. So, there has to be a proper system working to connect the working members of the company. Usually, the same departments have similar extension numbers and different departments have extension numbers resembling the company’s business number. This enhances in-office communication. Moreover, internal extensions work irrespective of geographical location. Employees working in the different offices in the different parts of the country can easily connect within a fraction of seconds (but in the same company). Also, they can be configured to multiple devices for the same employee ensuring lesser chances of missed calls. So, internally, phone with extensions increase efficiency and quick internal communication increases productivity and scalability of the company along with saving time and cost.
External Extensions: Whenever a customer, supplier or investor has to make a call within the company, they are generally provided with the business number.

According to the button pressing at the time of call, with the Virtual Receptionist, the customer is redirected towards the complaint department. Moreover, the order of phone numbers listed in the groups of department and ringing of all phones together upon the subject of availability of the concerned person is how the algorithm of external extensions works.
It can be concluded that phone number extensions, resembling telephonic extensions, as used in businesses, play an important role in internal communication within the company and external communication with the outside interested people with the members of the company. Whether internal or external, voip extension customizes the need for communication along with the turnaround time of communication along with the introduction of time-saving and cost-saving features.
