I am not very familiar with these systems but have already upgraded a customers Officeserv 7100 box to support up to 28 phones. It has a Uni card with 2 x 4DLM cars and a 2BRM card. It also has a 16DLI card and an MP10 card with MGI16 card, SVMi8 card and 4DLM card. I believe it will support more phones but am not sure what is required. Can 16DLI cards be upgraded?, if so how would you plug the additional handsets in. How easy is it to swap configurations from the 7100 to say a 7200?
