So here is the deal:
Have a client that needs 120 single line phones. They previously had a DSX. The SL-1100 cannot handle this amount of single line phones. They have 70 or so single line phones on the DSX, so that is plug and play. So I was thinking of using the SL-1100 and networking two systems together so I can get them to 120 single line phones. NEC says this will work, Interested in anyones thoughts on this?

Thanks
Walter
