To report a problem with the phone (echo, static, choppiness, no dial tone, hardware related problem, etc…) or request a change (extension, voice mail, caller ID, directory listing, etc…), please place a support ticket. The phone equipment MAC address helps our phone support team find the device on the network to remotely resolve issues with calling and access.
The quickest and easiest way to find the MAC address is to look on the back of the phone and locate the sticker often near the middle or bottom of the phone.
The MAC address will be listed in the format A1:B2:C3:D4:E5:F6 or A1B2C3D4E5F6
Alternatively, you can find the same information from the screen interface.
