Robo call blocking

I have noticed that in response to questions about blocking rob o calls that Cox has indicated that the question is being referred to phone development.  What is the status of this?  We are Cox customers for over 30 years but relatively recent digital phone subscribers.  The vast majority of our calls are sales pitches, scams, etc and we are seriously considering dropping the service.  Most of your competitors offer the Nomorobo service.   Will Cox soon be offering this service?  We are aware of your anonymous and selective call blocking services but they are not effective in addressing this increasingly annoying problem.  Thanks.
