I am trying to recycle a discarded Mitel 6920. I hope to use it to replace my ancient Polycom phone.
I have managed a factory reset to delete the previous user's details, and the phone now asks for the IP address of a Border Gateway.
The PIN number 73738 gets me into the "advanced" menu on the phone, but there is nowhere I can load the log-in details of my own SIP server.
Does anybody know the "Magic Incantation" to do this?
