Is it possible to block all private numbers from landlines?

Question

thank you all so much

Answer 1

yes, with *77 ACR...which is anonymous caller rejection!!

you will hear a stutter tone, so you know that you done it right!!!

many calls/numbers are still coming thru, because they are using virtual numbers......in that case you will need a callerID manager!!!

Answer 2

Yep, press *77 and all private numbers will hear a recording that tells them that in order to call you they must dial a certain number and show their number on your caller ID.

Answer 3

Yes, call the phone company, it will cost you though

Answer 4

With Qwest the answer would be yes
