Reach employees and departments
using their 4-digit extension.

With extensions, you can advertise a single phone number for your company and still give callers a way to get directly to specific employees and departments.

Cloud Based Phone System Feature: Extensions

Give everyone in your company their own 4-digit extension.

Every business needs a main company phone number that can get callers to any person or department. Tresta makes it easy to assign 4-digit extensions that callers can dial to go directly to a specific employee or group.

Extensions for users, departments, and forwarding numbers.

Every user, user group, and forwarding number in Tresta comes with an extension built-in.

Add as many as 9,000 extensions.

With a 4-digit numbering scheme, you have 9,000 possible extensions available to assign. (1-999 are excluded from the numbering scheme and cannot be assigned as extensions.)

Great for speed dial too.

Extensions are also a convenient way to speed dial other users and departments from within the Tresta mobile app.

We like being able to use the same phone number for everyone - it reinforces our brand and saves money.
