I keep receiving calls and when I answer they "put the phone down" and when I dial 1471 it says no number stored.. can I stop/block these calls ?

1417? sounds like you are in an extremely small Country to have only 4 digits.
Can you give that number a custom ringtone and select none?

1471... is a number you can call to see who your last caller was. It either tells you the number/says caller with held number/or no number stored... the no number stored is international and therefore annoying as I want to bar these as it will be tele sales anyway.

Honestly you can't, except by changing your number or subscribing to BT anonymous caller reject.

Thanks for the reply , but it's a business number and I'm not with BT now. I was paying to block number withheld calls ,but it doesn't stop international calls. I know it's a computer call... well I guess it is. It still is so annoying when I have to leave what I'm doing to have the phone "put down as I answer" grrrrr!

These numbers are used a lot by telemarketerrs and yes they are seriously annoying.
Might be worth calling your current supplier and see if there's anything they can suggest.

Already have and they said not really... just hoped someone had a trick to share... hey ho.. thanks for your help.

A couple of years ago I got repeated calls from a telemarketer, and I called my Cell Phone Provider and asked them to block ALL INCOMING CALLS that are anonomous or private, the said sure. After that I called my own number and found ALL numbers were blocked. They don't give a shix. It is minutes on their cellular. I have yet to find a cell company that has.
Personally I would ****can all in the Employees in the FTC. The can't control unwanted, unanomous calls, seems like a worthless group. If I am elected, We will fine these piece of craps and Make money, Not TERRRORIZE fellow Americans.
Yes, I am on the DO NOT CALL LIST.
