Cox Phone Upgrade Incompatible with Home Security System - Still

" so Cox needs to get their stuff together and do it right."

What would you consider "right"? Many security systems work just fine with non POTS phone. How would Cox even know which customers need assistance? 

"It is not that complicated."

I agree, that's why I don't understand why this isn't a simple fix for a security person. Lots of other providers besides Cox switched from POTS to packet switch. Did ANY of them "get it right"?
