Caller ID "VOIP CALL" I answered but I did not say anything. Voice recording said they were calling about home security. Then a different person spoke (live) and identified themselves and hung up. Another number for call block. About an hour earlier I had gotten a call from 866-349-3521 (a blocked number) which is a home security or alarm company.
Just received a call, but I didn't answer. I don't pick up unknown callers. They hung up. I'm on the Do Not call registry. I just blocked this number. Location identified as Santa Clarita, Calif.
