Called my home by 8:10 Am, we never answer unknown calls, did not leave any message. The number was not shown on my tv (at&t uverse) but my caller id showed this number and identified it as a wireless call.
Been getting a lot of calls from 951 area lately, sometimes 5 calls a day, and they never leave a message. As of today, I have changed my outgoing voicemail to a dis-connected recording, hoping that either the auto-dialer will detect the tone and remove me from their list, or that someone will actually pick-up, hear the recording and flag my number as inactive.
Knowing that most of these are likely spoofed numbers, I'm not sure about the usefulness of reporting them, although I may continue to anyway.
Stayed on the line this time until a human picked up. Some solar energy company. When asked to remove number from list, caller hung up. Calling back number on caller ID gets recording stating number is disconnected, so it's a spoofed number.
