I inherited a mitel 5360 through work that I want to use at home.
Problem is, I have a SIP setup at home and the phone isn't compatible with SIP.
If I switch it to SIP mode through the settings menu, after I reboot it does its DHCP business and says "install newer load." and then restarts after about a minute.
I figured all voip phones would have SIP support out of the box, but from what I'm reading, I need to update the firmware.
Is there a location for me to get this firmware?
