This article will tell you how to answer a call that is ringing on another phone.
First, you must have BLF Keys enabled on your account.
Ensure that you are monitoring the extensions you would like to be able to answer. You can select these under Admin > Extensions > Advanced Options > Lines.
When a call is coming in on one of the extensions you are monitoring, the line key for that extension will start to flash. You can then press this line button to answer the call on your own phone.
**This is currently only supported on Cisco & Polycom phones.**
