Duplicate MAC Address Error

Updated: 4/19/2024 1:40 AM

To add a phone to an extension, a unique MAC Address must be used. If you use a MAC Address that is already assigned on another extension, an error message displays.

Only the Super User and Administrators can correct a duplicate MAC address error.
