As others have already posted about methods to reduce the number of T1s into your Asterisk box, I will look at some other issues, and a differnt angle.

I'm open to suggestions. Remember you are dealing with Analog lines here. Most hotel rooms that have 3 or 4 phones, only have 1 "line". They just have multiple extensions of the same line. A hotel room with one phone in the bathroom, one next to the bed, and one on a table, still only needs one DS0 from your Asterisk system. Unless the hotel has a really large cable plant, each room probably hits a wiring closet on it's floor. I would use the channel banks, large UPS, and a decent asterisk server (dual power supply, server quality hardware, mirrored drives) with a Quad T1 card (or two) for that floor. I would then use dual Gig E to connect your system. Probably to two differnt GigE switches, each on different floors of the hotel. A 600 room hotel would have at most 75-100 rooms per floor, which you can easily handle with a single Asterisk server. Per floor, even with your Quad T1 card, you should be looking at $3000-3500 for the server, $1K for the UPS (unless you Ebay the UPS), and then your channel banks. The only issue here will be cooling for the wiring closet.
