Howdy! Wondering if any manufacturer produces a line of DIGITAL phone systems comparable to the quality of the discontinued Nortar CICS/MICS product line. I know Toshiba has the Strata line, NEC makes the DSX line, and ESI makes a digital-hybrid line of small office phone systems. But are any of these comparable to the quality of the old Norstar MICS/CICS line of phone systems? Yes, I know VOIP is the new standard, but what is the best option as far as digital phone systems are concerned that aren't EOS.
