Thanks for the welcome and both for the advice and help on the deal, well it sounds all fine to me, I just do not jump to quick I mean who trusts BT.
I will sign over to it which will make good protection if someone in the house calls without selecting from our phones phone-book which has most people installed as 1899 prefixes so it works well but on occasions that slips by.
Also thanks you for the link and tip on 1571, we have always said 7 rings is rubbish to get to the phone, it may be worth dumping the service all together like you said.
12 Rings would be great and the engaged tone but they would not make cash out of that, so we would not ever see that.
