Just a point about the Repliies 39 and 43 on that forum, by Anotherone.
He has it wrong.
BT Option 2 phone is £10.50pm rental if you take paperless billing and D/D payment. (I'm on quarterly billing but I think the monthly is the same). The Evenings and Weekend package is chargeable
if you take that package on its own monthly deal but it is
free if you take it on an annual basis. (Crazy but true).
Even though I have the Option 2 12-monthly Evening and Weekend package, the 12 months applies only to that aspect. If I got rid of my BT line it is 14 days notice and I would have to pay the balance of the 12-months E & W charge at whatever the rate is now after the Vat reduction.
Additionally (subtractionally?

) Caller Display is chargeable, except that too is free if your take the
free Telephone Preference Service to stop unwanted spam calls as it is included in that service. Again, crazy but true.
Drawback is I am finding the caller display is not reliable - some calls it picks up and others it doesn't. It only seems to work for a few days after I go into my BT Account and check the details, then it stops. There was something I read a while ago, just after the previous changes, that CD only recorded calls
arising in the BT network but that isn't the case when mine is working and would make it a laughable irrelevance if it were. Neither can I find that statement again.
