Consisting of an M300 base station and an M25 handset, this set is the prerequisite for a powerful and expandable mobile telephone solution. Up to 20 handsets can be registered to a single M300 base station, providing enough capacity for smaller offices. With a range of about 300 meters outdoors and about 50 meters in buildings larger areas are covered, which can be expanded with up to three M5 repeaters. This DECT telephone solution is easy to install and configure. The system is compatible with most SIP-based IP PBXs.
