What is a phone extension? Meaning, examples, numbers and morePhone extensions

If you’ve worked in a company, you might’ve wondered how they manage to route calls so efficiently ..and you’ve likely heard the term “phone extension” before.

But what exactly is a phone extension, and how does a phone extension work?

In this guide, we’ll break down everything you need to know about phone extensions.

What is a phone extension?

A phone extension is basically a short number added to your main business line, letting people reach specific employees or departments in the company directly. Think of it as a mini phone number that helps route calls efficiently.

For example, if your main number is 444-6789 and the extension is 110, calling 444-6789 ext. 110 will connect you straight to the sales team.

Extensions make it easier for both your team and your customers to get to the right person without the extra fuss. They’re especially useful in VoIP systems, where they’re just extra digits added to your main number.

How do phone extensions work?

Phone extensions are like short #’s that’s added to the end of your main number – makes it easy to reach specific people, teams or departments.

For instance, you might use extension 999 for customer support, 222 for sales, or 101 for an certain employee.

Mostly, phone extensions are normally used for two main purposes:

Employees: They let staff call each other directly, skipping the main number and making internal communication easier. With a virtual PBX like iTeleCenter, you can set up extensions across different devices and locations.

Clients: Phone extensions help guide customers to the right department or person.

How to dial an extension number

Here’s how to dial a phone number extension,

When making calls internally

When calling an internal extension from a VoIP or landline, you don’t need to dial the full 10 digit business phone number. Just enter the extension code directly. Making internal calls between extensions are free and don’t come with distance charges.

When making calls externally

For external calls (imagine a customer dials a reps’ extension), callers need to dial the full ten digit business phone number before even entering the extension. They can enter the extension code when prompted or directly after dialing the main number.

When making calls on your cellphone

• Open your calling app and dial the full 10-digit business number.
• If you’re looking toconnect directly to an extension, press * followed by the extension code, then hit the call button.
• If you don’t know the extension or say you want to hear menu options, press # after the 10-digit number and then place the call. Once you hear the right extension, enter it to connect.

When making calls from your landline

• Throw in the 10 digit phone number.
• If you know the telephone extension number, try entering it as soon as the call picks up
• If you’re not connected right away, wait for the prompt to enter the extension code.
