Our company is equipped with a Gigaset N720 DM PRO system (1 manager + 1 base station). We would like to extend the DECT coverage because our premises are large and some offices do not receive the DECT signal properly. We have tested the REPEATER 2.0 but it is not compatible with the Gigaset N720 DM PRO system! We would like to know which device to use to extend the DECT signal from our system to our remote offices.
