The 3CX Hotel Module is an add-on for the 3CX Phone System that turns it into a fully featured Hotel PBX. A Hotel PBX provides specific features for hotels like check-in/check-out, do not disturb settings, and billing calls to guest rooms. It allows hotels to eliminate expensive lease payments for traditional phone systems and cut costs on phone calls. The 3CX Hotel Module integrates with popular hotel software and supports reusing existing analog phones in rooms to avoid rewiring costs. Hotels using the 3CX Hotel Module have been able to reduce telephone administration costs while providing excellent service to guests.
