Blocking scam calls on landline

We get dozens of recorded scam calls every week. How do we block these on an AT&T landline? *60 doesn't work for this application (and only blocks 10 LOCAL numbers). Why isn't AT&T doing this automatically?

Let's help you stop these unwanted calls, @dgold!


While *60 is able to block up to 10 local numbers, we have multiple ways to block calls for your landline devices. For example, did you know that you can use *77 to turn on the ability to automatically reject calls? 


Let us know if this helps- we hope to hear from you!

I just received another scam call – caller ID said “Unknown Caller”. After I hung up I dialed *77# and as usual I received the usual “anonymous callers have been blocked” - but they aren’t!!I

ATT-Uverse does a poor job of blocking these scam calls – may I suggest instead of caller ID saying “Unknown Caller” have it say “Caution – Possible Scam Call” or is that too long? “Scam Call” is shorter. Please????

That only works for people who have caller ID but block it, like if you were to block your outgoing CID and whoever you called had anonymous call rejection activated. It doesn't stop those who don't send a CID to the phone company to begin with, which is what unknown caller or unavailable means.
