I didn't recognize the caller, therefore, I didn't answer the call. No voicemail was left. I do have a business. I received these type of calls very often. I have created a Junk Calls contact list on my smart phone, when they call again using the saved number, my phone automatically transfers the call to my voicemail and since they never leave a voicemail, my phone doesn't even registers the call as a missed call. Just FYI.
Wow, do you people REALLY think the "Do Not Call" registry works? LOL. Try this: if you see a number that you don't recognize, don't pick up. When they've hung up, come here and find out the caller. Then, go out and buy yourself a Sentry PlugNblock on eBay for about $40. Within 6 minutes of plugging in two cables, it silenced the very first robocall.
Not recommended for businesses due to the inability that it will not allow voice messages but if it's important, they'll call back. Plus, you already have their number in your caller ID.
Stop complaining and help yourselves. The government can't keep up. Anyone can now use ANY number to spoof and call you.It doesn't have to be their own.
