These are usually 'predictive dialler' calls made by call-centres that dialled more numbers than they have agents available to handle. Ofcom rules require any unanswered abandoned call to play a short identifying message; if it doesn't, you can report the caller to Ofcom.
If a 01777 237 XXX number called you and you're not sure who it was, the safest steps are: don't return the call until you've verified it (search the full number online first), don't share personal or financial details, and register the number with the Telephone Preference Service (TPS) if it's a marketing call. Persistent unwanted calls can be reported to Ofcom and the ICO. To block a specific number on most UK mobiles and landlines, you can also enable network-level call screening through your provider.
