Anonymous Call Rejection* (*77) – Traditional Landline
Anonymous Call Rejection* (*77) intercepts calls from people who have used a blocking feature to prevent their name or number from being provided to people they call. When Anonymous Call Rejection is activated, callers hear a message telling them to hang up, unblock delivery of their phone number and call again. Your phone will not ring unless the caller removes the block.

I have used *77 to attempt to block anonymous calls on my AT&T landline but continue to receive numerous robo calls each day (as many as 8 in a single day) where the Caller ID name is blank. Is there anything else I can do or AT&T can do to block these Anonymous Calls? Evidently *77 doesn't work even though the description of Anonymous Call Rejection says : "Prevents anonymous calls from callers who block delivery of their Caller ID information (name and/or phone number)".

We apologize for the inconvenience with anonymous call rejection issues. Visit this article help and understanding of why some calls don't get rejected by feature.

I tried *77 on my landline and received an error message that it is not available. This is a traditional ATT plan, so how can I get this service started?

I have a traditional ATT landline and the *77 returns an error message that the service is not available on this line. We are in a major city (818 area code) so what can be done to solve this?

I get the same message when I try to use Anonymous call rejection by putting typing in *77. Its maddening to say the least.Being on the governments Do Not Call List either. They don't do anything to the people making the calls because we still get them from the same numbers that we reported to them. That's what happens when the government decided it was okay to release everyone's phone numbers whether they are Landline phone#'s or cell#'s. We don't get privacy anymore.

You'd be better off posting you question in the wireless forum. I believe call protect is available for cell service, but I'm not positive.
