π Understanding Phone Lines and Extensions
What Are Phone Lines?
In the UsVox system, Phone Lines are also known as Account Numbers. Each phone line represents a unique number that can be used to:
- Connect to an Extension (assigned to a userβs desk phone or softphone)
- Ring a Hunt Group (calls delivered to multiple extensions)
- Send calls to Queues (for organized call handling)
- Connect to an IVR / Auto Attendant (for automated call routing)
π How Phone Lines and Extensions Work Together
- An Extension is an internal short number (e.g. 101, 102, 200) that users dial inside the organization.
- A Phone Line (Account Number) is the actual SIP account registered on a device (desk phone, softphone, app). When you assign a Phone Line to an Extension:
- Calls to that extension will ring the linked device.
- Voicemail and personal settings follow the extension.

β Ways to Use Phone Lines
You can use your Phone Lines in three main ways:
1οΈβ£ Assign to a User Extension
