They will probably be centrex lines. have you tried to get the person in that room to find out if the number is maybe different than what it is supposed to be. I know that the uni's can have loads of lines and sometimes they get changed or if t gets disco's the reconnected they sometimes end up getting a different number allocated. The uni would have to contact NTL business's cust service to find out if there was anything wrong.

If you want to PM me the details of the tel number and room No and I will see if there is anything I can find out about it for you when I am next in work.
