My office is in the process of moving and needs a new phone system. We have had comparative bids from NEC (Electra Elite IPK) Comdial (DX-80) and Intertel (Intertel Access). I need to know any pros or cons of these systems. Which system is going to work best for my office(New office will have my business and a tenant. 18 handsets and about 10 lines.) Any suggestions or info would be appreciated.
