Dear Cox, why is my blocking phone number ability limited to ONLY 30 numbers? I must get three spam calls a day and must clear the numbers too often. How about UNLIMITED blocked numbers ? PLEASE!

"...most current information on spam callers..."

Known spam callers?  That's now an oxymoron.

There is no current information on spam callers.  Spammers use spoofed numbers like bullets:  use it once...reload another.  Since Nomorobo launched on 1 Oct 13, my one-time spoofs increased 365 percent.  In the past year, I've received 178 of them.  That's probably much fewer compared to others, but I don't give my number.  If Jiffy Lube insists, I blatantly give a fake one.

Nomo can't block one-time spoofs.  Cox has to be proactive.  How?  Perhaps a proactive lookup.

If a number has never connected to me before, force it to enter a CAPTCHA.  "Connected" meaning I picked up the phone.  No CAPTCHA...block it.

Who enters the City & State in the Caller ID...Cox?  Perhaps that could trigger a lookup.

If I get repeat calls from Lupus, BBBS, Unknown Name...that would be up to me to either locally block or report.  The unknown one-time spoofs are the problem....not the known ones.

Our online Phone Call History should be more interactive.  What's does it currently do...list calls and add to Contacts?  Weak.  We should have a button to block.  Stop charging us to block!

We should have the option to block the known anonymous names (Name Unavailabl, Private, Unavailable, Unknown, Unknown Call, Unknown Name).  Allow us to report new anonymous names (Private Call, Unknown Caller, Secret Name).

Cox should use these known anonymous names with wildcards (*unknown*, *name*, *vail*).

We should have the wildcard option (*lupus*, *bbbs*, *pickup*, *cox*).

Automatically block unassigned Area Codes and Exchanges.

Bruce,  you have summed up the problem succinctly.   I only block spammers if they call a 2nd time from the same number.  I bought a home phone that blocks 250 numbers.  If I block the "one-time-spoofers", I can fill up the 250 spaces in a few weeks.  Yesterday I had 4 one-time spoofers.  Today I'll probably receive 5 more. 

I got tired of limited blocking, bought an ATT phone that won't allow any calls to come through unless they are on allow list.   When someone calls not on the allow list, they are prompted for name and then must press # key.  Then it will ring and I get 3 options to answer once, answer and allow or block. 

This has stopped all robo calls and there is no limit.  Amazing how many calls I see blocked and the phone never rings.

Sounds like a great phone.  I've been Allow Listing since 2011, and it's been great.  The biggest benefit is not having to purge my answering machine of robo messages.

I recycled a WinXP laptop with a built-in dial-up modem.  I loaded a call-blocking program, connected to a phone jack and have been blocking everything since.

It takes a bit of homework to research call logs for potential "friendly" calls but it was worth it.  Besides, it's easy to allow a number after being blocked.
