If you didn't recognise the number, why on earth did you call back?

I know..I know...should not have phoned back....but it was instinct......

"0121 708" is a BT allocated number from 1994. Possible it is now owned by someone else, but you never know. Could be a business or personal number... if it cuts out dead, it is likely to be an outgoing call centre number.

Hi BM,

Have you signed up as a phone number that does not accept junk/spam calls?
I won't stop organisations with whom you have had a relationship (eg a charity) but it will much reduce the problem of:
"Your are waiting for an important 'phone call, but you have just got in the shower, when the 'phone rings and yes dripping with water, there is no point in trying to sell you double glazing, because ........".

If you are on a land line do a 1471 to double check the caller - it it is unknown or withheld or different I would not call back the number in the message. But in a household with several adults in it, it is sometimes difficult to understand for whom the message is intended.

PS Not wanting to hijack your your thread; I have had two unwanted calls from a number starting 0795.........
which I would think was something to do with mobiles(?!?) Can someone point me at a link to the meanings of all the prefixes.

I was just called on my BT line by this number 0121 708 4055 too.
I answered and was asked if I thought my bank had over charged me.
I said no, and the man hung up, how rude!!
I called the number back and got a message saying something like ocean consumer research.
I've already gone through all the BT options, months ago, to stop these calls but still the odd one seems to slip through.
I hope this helps you out.
