Why is call blocking limited to a mere 30 numbers?

Why is the call blocking and call accepting features limited to a mere 30 numbers?  I get SO MANY unwanted "sales" calls that I quickly filled up the 30 limit and then the rest can get through.  This is 2019.   A 3000 number limit would not take up any space what-so-ever on a modern day hard drive, for example.  This 30 number limit dates back to the 1990s as far as I know.  Why has it never been increased?  100 numbers even would help.  30 is just far too limited. 


It's not just Spectrum either.   My son's cable company phone has the same limit and it seems utterly arbitrary and carpricious at this point in time.  I had to switch to accepting only 30 to block all the other numbers.  Now I'm quickly approaching the 30 accepted limit and so it's the same in reverse, not to mention it blocks emergency services as well.  But that seems to be the only solution to almost unending daily robo, charity and sales calls that routinely ignore or get around the government's "Do Not Call List", which has only limited effectiveness.

    Spectrum has Nomorobo, which blocks calls from telemarketers and spammers after the first ring.  The number shows on your TV, if you have Cable TV and Caller ID on TV turned on.  The Nomorobo zaps the call after the first ring.  We have had it for three years with Spectrum, and I think at most TWO calls penatrated the system by being able to leave messages!


    Calls regarding weather emergencies, doctor appointments, schools, are allowed through.  You need to first turn on Nomorrobo:


    1.) Log in to My Services

    2.) Go to Home Phone Settings

    3.) Under "Peace and Quiet" turn on Nomorobo

    4.) Say Yes to "Answer Anywhere" being activated, if prompted

    5.) Save your changes.


    Nomorobo is working when a caller can't leave a message after the first ring.  Sometimes, the phone needs to ring a second time for Nomorrobo to screen the call.  Make sure you don't pick up the phone till at least after the first ring, so that the call can be dropped if it is a Spammer, Robocall, or Telemarketer  It hangs up on all those types of calls!


    If a known Robocaller is able to leave a message, you can report the call to Nomorobo at their website with a Nomorobo account. (Different than My Account at Spectrum.) or Follow Nomorobo on Twitter and give them the phone number that isn't being blocked so they can investigate.  I have only had to do this twice in the last three years!  It's that good!

    This limit is ridiculous!!! Got 24 junk calls already this week alone! Besides the 30 call limit on call blocking being inadequate, the numbers on other "services" like call forwarding is also inadequate!

    Spectrum doesn't seem to care about doing something to limit these calls. They SHOULD be blocking calls from invalid area codes and prefixes.
    Bottom line is Nomorobo and Do Not Call list are a joke and do very little to thwart these nuisance calls.

    Nomorobo far from perfect and does NOT completely block these calls! Your phone still rings! While it's true that Spectrum has no control over the way Nomorobo works, Spectrum should be doing more to limit these calls. I've received quite a few calls from invalid area codes and/or prefixes, "spoofed" caller ID's, calls from numbers that are out of service.

    If you would prefer to use the Accept Selected Callers list you can enter in 30 specific numbers from which to receive calls.  This would not work if you have and extensive

    list of folks you want to come through this may not be optimal for you, it is an option available however if you are interested.

    While I appreciate hearing a positive story from some people about Nomorobo, the fact is that many people experience more calls than the system can handle. 


    In addition to needing to block more than 30 numbers, wildcard blocking is also needed. I would like to block,  for example, all numbers in a series like this:






    Frequently, I’ll receive a call a day from different callers with a number series like this.


    Finally, why should I have to manually enter the number in the database? Allow us to see the call record online and select “block this number”.
