Phone extensions: Overview

A phone extension is a short numeric code, usually a few digits, assigned to a specific user, team, or department. Callers enter the extension using their keypad to be routed directly to the right destination, without navigating a full menu.

Phone extensions are typically added to the end of your main business phone line.

For example: +1 (941) 487-0938 x356.

In DialLink, extensions are optional and are not enabled by default.

One of the most common use cases is assigning an extension to a user or team and sharing the direct number with callers. This lets them bypass the auto-receptionist or phone menu and reach the right person or department immediately.

Alternatively, if you use an auto-receptionist or IVR menu, you can let callers know which extension to dial to reach different people or departments once they hear the options.

Internally, extensions let you call teammates or transfer incoming calls just by dialing a short code from the app or your desk phone.

In DialLink, you can assign an extension to the following entities:

Phone extensions are available on the web browser version, desktop and mobile apps, and desk phones provisioned with the DialLink system.
