Managed Voice / Extensions & Phone Numbers

Extension Management

You manage extensions (the internal short numbers assigned to people, devices, or departments — see Glossary) directly in the web-based admin portal. Adding a new hire, removing someone who’s left, or reassigning a number to a different person all take minutes. You never need a technician visit for any of it.

What can you configure on an individual extension?

Beyond the number itself, you can configure the person’s name and voicemail greeting, which devices carry it, and its ring group and department memberships. You can also set permissions, like international calling, plus its own call-forwarding and do-not-disturb settings.

Can one person have more than one extension, or one extension on multiple devices?

Both are supported. A person can register their extension across a desk phone, a desktop softphone, and a mobile app at the same time, with all of them ringing together. In some cases, we can also set up a second extension for a distinct role, like covering a shared support line.

How quickly does a change take effect?

Changes made in the admin portal typically take effect immediately or within moments. So there’s no batch process or scheduled sync to wait on, even for something as routine as updating a name, a greeting, or a forwarding rule.

Can you organize extensions by department or location?

Yes. You can group and filter extensions by department, location, or any custom grouping you define. That keeps management simple even as a business grows to dozens or hundreds of users across multiple sites.

What happens to voicemail and call history when you reassign an extension?

You control this directly. Reset the voicemail box and history for a fresh start with a new employee, or keep them if you’re simply renaming or reassigning the extension within the same role.
