*60

I have this service and must say that is a ridiculously small amount.  I had it filled up in 2 weeks. 

The Cox feature works well but the max is 30 phone numbers. Far too few to help me eliminate the spam problem. I bought a new home phone that has the ability to block 250 numbers.  That is working well.  I think i read that the newest model can block 300 numbers. 

Thanks to all...yak, can you tell me what phone you have?

I saw articles online about the ability to block 300 numbers.  The phone is a Panasonic ( i don't work for them or promote their products).   I got it on Amazon for $80.  Read the reviews.  Every 8 months they make a new model.  They add 2 neat new features but remove one popular feature.  The reviews will help you decide which things you want or need.   My phone blocks 250 numbers.  I don't block any spammers on their first call.  I write down the numbers and block it if they call back.  More than half of the spammers change numbers every day.  It doesn't help to block a number they've already abandoned.   My brother bought the $25 Panasonic which blocks only 60 numbers.  

My model is a 2014 KX-TG 7871.  It is already ancient history.  They have 3 newer models. 

When you buy the phone it is pre-set to ring once before the call is blocked.  You have to go into the Menu to turn off the ringer . Peace and quiet.
