AI Summary
Based on 1 community report
This London number has so far generated just one report, in which the caller rang but said nothing — leaving only silence on the line before the recipient hung up. With no upvotes or downvotes, there isn't enough community confidence to say much with certainty. Silent calls like this are often the result of automated diallers testing whether a number is active, and can sometimes be a precursor to more targeted nuisance or scam calls. The spam score of 44 out of 100 suggests some level of suspicion, though it's far from conclusive. If you receive a call from this number and experience the same silence, it's worth hanging up and considering blocking it.

1 totalThey called, I picked up, but there was nobody on the other end, just silence, so I hung up. Unless they talk, we don't know who they are. This is happening a lot lately with these so-called calls. Could be debt collectors, housing social services, life insurance, and it could go on. Just junk mail like it used to come in the post, but now it's through technology. Why Ofcom can't deal with this, we never know. It's about time something was done about all these fake phone numbers being made.
