Firstly the company doesn�t really work like that, tends to be more reactive than proactive. Secondly-how many lines do you think a hotel would need? Only a few I�d have thought.
A hotel is probably going to use ISDN for telephony I would imagine. They aren't going to have a whole bunch of separate pairs from a PCP.
Could even use SIP via a third party via EFM / xDSL.
