Single-user license module for concierge in IP EVO systems. It allows a station that provides many functions: intrusion into all the calls from IP EVO external stations to internal units, both physical and virtual, pass-through function, time-slot scheduling, call hold, call forwarding from external units to internal units, event log, missed call management and door opening. All functions are available both from a fixed station via a web browser and remotely on a smartphone using the IP EVO app.
