Comparison

Requirement	PS 64	PS 112
I want to offer my guests voice mail
I want to give my guests the option to either set their own wake up call or have the front desk do it.
When things get busy at the front desk, or at night, I'd like an auto attendant to answer.
I need call accounting with credit limit and auto shut off.
My Property Management System (PMS) needs "costed-call" data from the telephone system for posting to guest folios.
The franchise requires answer detection for billing accuracy.
My property is serviced by a T1 trunk line.
My PMS system can connect to the telephone system and check guests in and out.
I have more than sixty rooms.
My franchise requires two lines per room. If the first is in use, the second will ring.
My administrative users need to answer calls ringing on other extensions and have access to single-button features like Hold, Do Not Disturb, Transfer, and Redial.
