im confused!

[missjef]

does any one have this? http://www.productsandservices.bt.com/consumer Products/displayProduct.do?productId=CON-3399 is it free to sign up for this and have free caller ID? it seems to be... but i'm not sure!

ps. what does it mean by chargeable calls? is that just any call that you'll get charged for even if its just to another house in the area?
many thanks x

Free caller ID has been free with bt for quite a long time.
