A prospective customer has an old BT Inspiration system. When a new guest arrives, he dials a code to activate the phone in that room, and when a guest leaves, he dials another code to check the guest out. Doing this causes the printer attached to the PBX to produce a bill. With 3CX, there are complex hotel integrations - but in this case, the hotel is too small for this, and doesn't have a such a system. What I need, is a way for the hotel receptionist to print a phone bill for a particular guest. The daily reports aren't good enough, as they show multiple extensions and are automatically generated each day - we would want to generate the phone bill at the end of the guest's stay, which may be a day, or may be a week. Any suggestions?
