Check for loose or disconnected connections in the phone. That's what I'd do first. Also check your power supply, if it's the type with the screw terminals on the power supply block, make sure nothing is frayed, etc.

One thing you could do is get an analog phone card (or some ATAs) for your Nortel system and they'll work in conjuction with each other. You can enjoy the old and the new at the same time... I did this with my 1A2 and Avaya Partner system.
