Simplify Internal and External Dialing with Phone Extensions
When a caller already knows who they need to reach, getting there shouldn't take long. That's what a business phone system with phone extensions does: assign a short code to every user, team, or AI agent, all reachable through one main number. Callers get where they need to go faster, and internal transfers take less time.

Let Callers Reach the Right Person Directly
Callers who already know who they're trying to reach can dial straight to that business phone extension when they call your main line, skipping menus and transfers entirely.

Transfer Calls Faster between Team Members
Give your team an even quicker way to transfer calls to a user or team by simply dialing a short code, whether they're in the app or on a desk phone.

Frequently Asked Questions
How many digits does a phone extension have?
Phone extensions are typically short, three- to four-digit codes, making them quick to dial and easy to remember. With DialLink, you have more flexibility, extensions can be anywhere from three to six digits.
How many phone extensions can a business have with DialLink?
In DialLink, you can have unlimited numbers of extensions for one business phone line.
Is a virtual phone number the same as a phone extension?
They're related, but not the same. A virtual phone number is an actual phone number, used to make and receive calls just like any other number. An extension is a branch that exists under a phone number, a short code that routes a call to a specific user or team without needing a phone number of its own.
Can I use extensions on different devices?
Yes. You can use extensions from DialLink's mobile app (iOS and Android), desktop app (Windows and Mac), or a desk phone.
What can I assign phone extensions to in DialLink?
You can assign extensions to individual users, ring groups, call queues, and AI agents, all under the same main phone number.
Do I need special hardware to use extensions in DialLink?
No special hardware is required. Extensions work through DialLink's mobile app, desktop app, or desk phone, so you can start using them with the devices your team already has.
