We have run out of space in our phone system (Telrad 128) and are looking at a solution of moving to a 400 system. I have asked this question before but it was over a year ago, and now we have to move.

My questions is what do we need to do to our old 128 cards to make them work in a 400 with version 7.2? Where do we find the parts and what will it cost approx. per card.

Thanks,
