AI Summary
Based on 1 community report
This London number, routed through Belgacom International Carrier Services, has received one report describing a missed call with no voicemail left. With only a single submission and no community upvotes or downvotes yet, there's limited evidence to determine whether this is genuinely suspicious or simply an accidental dial. The spam score of 62/100 suggests moderate concern, but this could reflect the call's international routing rather than confirmed malicious activity. If you don't recognise the number and didn't expect a call, it's reasonable to be cautious about returning it. Consider waiting to see if they call back or leave a message before taking action. If calls persist and you remain unsure, blocking the number is a safe option.
