Like a persistent doorbell that refuses to quit, these rapid‑fire calls can feel invasive and confusing. The pattern you describe—multiple rings in quick succession, followed by a text‑to‑speech message saying the line is unavailable—matches common harassment tactics used to test numbers for future scams. Avoid returning the call; callbacks often confirm a live line for unwanted follow‑ups. Immediately add the number to your phone’s blocked list and consider enrolling in a national Do Not Call registry. Use call‑screening apps that flag unknown or suspicious callers, and report the activity to your telecom provider or consumer protection agency. Staying proactive reduces the chance of escalation.
Multiple calls arrived within a short timeframe starting this weekend. When I called back, a TTS voice with a US regional accent said, "This number is not accepting calls at the moment." The same behavior occurs with 077 099 6957.
