I appreciate there is a hotel module with integration to different PMS, however, many very small hotels don't use a proper / supported PMS. For them, they simply want a PDF phone bill when the guest checks out. A lot of guest houses in the UK use something like the BT Inspiration system, and it does this: When a new guest arrives, the receptionist dials a code to activate the phone in that room, and when a guest leaves, they dial another code to check the guest out. Doing this causes the printer attached to the PBX to produce a bill. 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.
