I sleep just fine since I got a Panasonic phone-you can set it to block incoming calls during times you want to sleep and you can block nuisance calls one at a time. I do not answer unknown calls and block ALL that leave no message. It's pretty quiet around here now. ZZZzzz
I received a call from this number. Have no idea who it is. I do not answer unless I know the number or am expecting a call. I did recognize the area code as being in Texas, which I found weird. Tried reverse look up only got town am not paying to see who it is. I am on the no call list, so this kind of upsets me.
