Firmware upgrade for Mitel 5220
« on: September 24, 2012, 12:23:54 PM »
We have a few Mitel 5220 phones that have SIP firmware of 01.XX, and we need to upgrade it to at least version 4.  Is there anywhere I can download the firmwares in between since the mitel site ( http://sipdnld.mitel.com/ )went offline?
