Wow, PPC? I once had a Norstar NAM for voicemail, and did connect a monitor and keyboard and witness OS/2 on that. I think the NAM was an x86-based system. But I know the Meridian PBXs themselves were completely distinct from Norstar that I used. Never knew Nortel used PPC. Very neat!

Though my time with them came only as non-IP phone systems started to be considered obsolete, I am still a huge fan of the rock-solid stability and realtime speed of those digital systems. Not to mention their lack of a need for subscription services to operate.
