I have a Mitel 5000 with 5330 phones throughout the office. I purchased a new phone from Amazon for a new employee, plugged it in, set the static ip, gateway, etc., and everything seemed ok, display is good, no error messages on startup.... but when the phone rings the employee cannot hear callers and the end user doesn't hear my employee. There is no audio either way.
I am no expert by any means so it may be a simple solution but any help is appreciated. Thanks so much.
*Note - this is on both extension to extension calls and to external calls.
