Using a phone like the BT4600 will help, and genuine callers, who are not yet stored within the phone`s directory, will not mind announcing themselves first, as I posted here
I have now had 4 phone calls saying the same thing. A recorded message but each time I have barred the number they come back on a new number. They really should be blocked at the exchange end. It’s very persistent and phone calls are coming through at all times of day - some very early.
The numbers are spoofed using VoIP systems. They can't be blocked at the exchange end (not sure what you're referring to here ...). Unfortunately it's a worldwide issue that at present can't be stopped.
For example the 01384 number is a protected range (in other words not used).
The scammers will simply keep trying, and spoofiing different numbers to get around any blocking systems.
Go back to Page 1 as this is an old problem. Basically, once you answer the phone, your number is on their list. Use the block call feature on your phone if you have it, I do but still get two calls per day. I just turn my volume button right down as I don't hear it.
July 2nd, 9:00am....2019 I just got one of the fake callers telling broadband about to be cut off. My telephone identifier had a local STD number but the display said INTERNATIONAL....so probably some c**t from India or Russia.
Rule #1 is if it sounds dodgy it almost certainly is
I got two of these today. Caller display just lists these as 'International' which is a bit of a giveaway - why would BT be calling from abroad?
I've reported them on the BT scam line. The numbers were 07419246224 and 07459437752
I ignored them and hung up. I suspect that if you press '1' or '2' as requested you'll get a recorded rambling on a premium service line racking up the charges to their account.
