How does an extension work

1. How does an extension work? The extension of a telephone number is used by SMEs and large companies to assign a unique number (usually between three and four digits) to each employee's phone. Most companies have a single telephone number that, if it were for all employees, would ring simultaneously. Thus, it is possible to identify phones with different extensions that are connected to the main number. By doing so, when a user calls the company and chooses the department they wish to speak with, we can direct the call directly to the right person, saving time and gaining effectiveness and a better impression. In addition, extensions save us from having to set up a separate telephone line for each employee. To make internal calls, dial an extension The advantage of having telephone extensions is that we can make internal calls very easily. By calling the extension number we will contact the person we need to speak with, rather than memorizing a long number. Additionally, if a customer or supplier knows the extension number of that employee, they will be able to contact them directly. A PBX provides this capability to have VIP customers or to give special treatment to those who are most important to us, by giving them the extension number of the person in charge of their account. What is the extension number? It is very easy to call a telephone extension. Most of these types of calls are made within the same company, so if you need to contact a person whose extension is, for example, 0004, you need only dial 0004 on the phone. To call an extension from outside the company, you will need to call the main number first. Most answering machines will ask you to dial a few digits, or if you know the person's specific extension, you can ask the customer service assistant to connect you.

2. Add an extension To change an extension number or perform other tasks such as forwarding an extension to a specific mobile or another phone number, simply contact your VoIP provider, since they are responsible for everything PBX-related. Within minutes, you can change the extension number, cancel the extension, or add a new extension.
