Medium systems used in industrial applications are those that typically employ between 10 and 60 people. They generally have a dozen or more analog phone lines, an ISDN-PRI circuit or SIP Trunking. Phones are normally placed on every desk, in the Break Room, in the Copier Room and sometimes in the Front Lobby, Will Call area or shipping dock. There is usually a need for some number of integrated wireless phones. Medium size systems tend to lean toward the KX-NCP500/1000 series or the KX-TDE100. With Medium sized business, there is often a need for some number of VoIP Off-Premise Extensions such as a Manager’s home, a remote job site or a warehouse across town. Any of our Medium sized systems have this capability.
