On a landline. Most Google responses were for a cell phone. Making it more difficult, I have answering machines in my home and adjacent office so would need two of the devices or whatever. My answering machines don't have any call blocking utilities. The phone service is CenturyLink.
If your phone is through the internet VOIP it may have the same features as mine. I have Spectrum and you can get on the internet and tell it to block known robots. My phone will ring once and quit on those.
Bingo. That is where I would start. And if his current VOIP service doesn't have decent blocking, he could switch to another VOIP. Ooma, for example is low cost and has an array of call blocking, both custom where you enter numbers and known robo call list based.
I found it almost useless, except for blocking legitimate calls. The junk callers change numbers too often. What I really needed was a device with a whitelist, that blocks all numbers except those I want.
I now get one ring only on my home phone except for calls I want.
Usually. I do get a few that leave messages usually those that don't care. The first of the message will be cut off (the idiot doesn't care to wait for the beep). For example "...ess 4 to speak to an operator (long pause since the idiot doen't care this is a machine)"
One important advantage with a landline is you get NAME on the caller ID. This has allowed me to recognize most of the calls I didn't want to answer like:
UR POLICE ASS
AUSTIN TX
BREASTCANCER
TOLL FREE CALL
SURVEY
EASTER SEALS
DENVER CO
IRM INC
#1 is a charity or scam, #3 probably is too
#6 is a real charity, probably trying to treat me like an ATM. My answer will be NO.
#2, #4, and #7 are almost certainly junk calls
#5 may actually be that. I'm still not interested
#8 meaningless letters, probably junk too. I'll answer if I'm familiar with such a company
Note that #1 was probably abbreviated to fit short CID displays
I've had those too. When I'm out I get a call on my cellphone that claims to come from my home phone. That bot does leave voicemail, which seems to be a poor attempt to trick me into thinking I just called voicemail. The fake voicemail sounds drunk.
That'll work, although with Spectrum doing it you won't know the callers you want but didn't expect (like your doctor calling from a number you didn't know he had). With what I have, I at least get to look at the caller ID after that one ring.
