Meet your growing business needs with this expandable 4-line corded phone. The system is expandable up to 16 base stations, and each base station can expand to include 1 DECT 6.0 expansion handset (not included).
You can only use one line at a time. We tried one base unit and remote-it doesn't make a difference. Hooked up to base units, trying to use one remote-still said "base unit in use". Sucky phone-don't waste your money.
