I don't understand the OP issue, but I got a sleazy scam call from some company paying Century Link to have access to CL numbers.
I got a message on my voice mail starting with "Urgent! We left you a message you didn't respond to. This is about your Century Link phone service."
First off, the phone never rang. These assholes inserted the message on my voice mail without actually calling me. Then they went on impersonating being from Century Link when they are a completely separate company. They wanted to sell me a magical service that could block all spam calls, be the callers used fake numbers or other tricks to disguise the caller, and somehow this company could detect all those without blocking some of my clients. I doubt it. Probably they diverted my calls and asked people to prove they were legit callers.
That would suck with my business, people are calling for urgent medical problems.
And not only that, more than half the junk calls I get are from Century Link subcontractors claiming I could get a cheaper service through them (it's a scam, you don't get a cheaper service). Were these jerks who were claiming to be able to block all unwanted calls going to block Century Link sales calls?
Not likely.
Sorry, Rant over.
