The 0870 number you call, is not her real number.  There is a geo number that it sits on top of, and it is that number that would get the phone bill, and would appear on any CLI for outgoing calls.  Naturally, I would imagine that the number would be witheld.

Also, as it's part of a switchboard, it would be an internal line, and probably not easy to set up.

Never register a shared line of any type to an Indirect Access code like this (eg 1899).   Once it's registered all calls from the line (via that access code) will be billed to whoever registered.
The registered number is often likely to be a common number for a group of lines  and calls from any line in the group (eg. anywhere in the Halls) may also be billed to whoever registered.
Doing so might also be prohibited by the University, in the terms on which it provides the telephony service, if that's the only way it's got to avoid ending up with the bill itself.

Well worth looking at a VOIP solution.  All students have a network connection in their room these days and most and run a PC during waking hours.  Skype would be the simplest to setup (you will need it at your end too)  but there are other options possible.

No call charges at all, just a cheap headset to buy if you haven't got one already.

The IT department of the Uni will give you advice on other options such as getting an FWD or VOIPUSER number and running Xlite or a similar softphone. (Free download & free calls between users in the same system).

Hint: 1899 isn't a CPS service - it works by use of a prefix (1899) ;D.[/quote]

Well, well. Right enough. So it isn't.    Thanks bigjohn. That'll teach me to show off my misunderstanding of Telecom Industry terminology.  (I wonder why 1899 don't offer the 'convenience' of having the local exchange dial it for you ? )  Let me have another go at getting it right.

It's because they have to pay a large amount of money for the benefit of CPS on their service and then a couple of quid for each CPS customer who signs up.  For a company like 1899, this wouldn't be worth it and if they did go for CPS, their low call costs would most probably disappear as they would take forever to recover the costs of the CPS setup.[/quote]

That's perhaps Just as well.
The whole CPS thing (when done automatically at the exchange - [i]instead of dialling the code yourself[/i]) is just another area for taking advantage of a bamboozled joe public.
Perhaps I'll sign up with 1899 then, confident that they aren't going to surreptitiously(sp.) pinch all my calls

Also for whatever reasons 1899 are more expensive than BT for 0870 and 0845 so you wouldn't want your calls to be routed with them when calling those numbers.  But shysters like the Post Office and TalkTalk still carry these calls due to CPS being in place and then charge more for the privilege than BT.  You can get round this on a CPS line by dialling 1280 to force calls to route with BT but most "Joe Blow" customers aren't aware of any of this.

Strange thing about 1899 is that sister Finarea companies like 18185 and dialaround carry calls to 0870 cheaper than BT.  I can only assume this doesn't happen on 1899 in the hope that customers forget and so they get back some of their cheap fixed 3p calls to 01 and 02 numbers that way?
