Some bloke wanted to upgrade the scam protection on my phone line. If I have it then it obviously doesn't work, because his call got through.

Another look-up site claims this number is being used in a 'Call Protect' scam. They are claiming that they can cut down the number of scam calls etc. Load of CR&p, they are scammers playing people's fears etc and no doubt emptying your bank account or passing you on to other scammers.
