AI Summary
Based on 4 community reports
This London number appears to be triggering automatic spam filters from phone providers, with multiple reports describing calls flagged as 'Probable Scam' by network security systems. The behaviour described is typical of automated testing calls - checking which numbers are active without leaving messages or speaking when answered.
While none of the reports describe a specific scam attempt, the consistent pattern of provider warnings and silent calls suggests this number is likely part of a larger operation gathering active phone numbers. These details are then often sold to other scammers or used for targeted fraud attempts later.
Since your phone provider's spam detection is flagging this number and the caller won't identify themselves, it's best to block the number if you receive similar calls.
