What can I do with User Extensions?

  • Log into the mobile app, IP phones, and softphones with a single login.
  • Make and receive calls on your Telzio extension from any location.
  • Dramatically reduce costs by eliminating individual user fees.

Use Case

Using the same extension on multiple different devices is useful for employees who use both a desk phone and their cell phone, and want to have all calls and messages on both devices synced. Being logged into multiple devices also allows calls to find you, whether you're at your desk, or on the road.
