The mitel guy
Programmer
If you're interested in learning how the passwords can be reset on a mitel sx200 El ml ICP MX ax and CX, or if you would like to know how to change your system licensing. The systems are no longer supported and Licensing is no longer available as far as I know. So I have one single video on my YouTube channel and I will post the link to that video it is short and the comments there may help.
