Thanks,Rereading, I don't think I explained it very clearly. It may have read like I was saying the recipient of the call needs to hit a button to let the call through. But actually, it is the sender of the call. So if it is a robot, it cannot press the button to make the call go through. Just like the "I am not a robot" web site tests.
No, I didn't think your protocol was the same as mine. It's different and I say use what works with spammers to get relief. I understand what you do may be is different and I didn't want to imply one technique is better than another. If I get to my phone with my CPR unit on it with a strange number coming across, I can hit a button on it to block the number from future calling before even answering. Kill'em no matter what protocol one uses to get relief. I'm open to better suggestions. I had four one call rings today. Of course, I couldn't get to the phone in time but it doesn't matter as the calls were probably coming from a spammer random dialer.
I don't jump up to the phone anymore unless it gets past 3 rings although if I'm nearby and recognize on caller I.D. it's someone or a business I deal with, I pickup on it quickly. Use what one needs to use to get rid of this spammer menace. I wished the CPR had more memory to store more numbers to block. I have a recording machine on the line so if they want to leave a message, fine by me.
The only messages I get recorded are from family, friends and businesses I deal with. I tell businesses to leave a message on my machine if I'm out and I'll get back to them when I'm seeing them in person for the first time. I give them permission and know their number.
My mentally handicapped son was trained by my now deceased wife to never answer the phone. We taught him how to call 911 and call out. One time I was late at work, after my lovely wife died and was gone for a time. He called me from the wired home phone to my cell asking, "Dad, when will you be home?" I smiled as I answered and told him I was going out the door as I was indeed in the midst of doing. Glad my lovely wife taught him to do that!
