I'm been having a similar problem for over a year now. My Call Waiting toggle show OFF, but call waiting is ON. I want Call Waiting to be OFF. If I try to flip the switch on the web page I get a message to try again later. Cox support can duplicate the problem using my user ID and password, but they haven't been able to fix it.
I'm not 100% sure, but the problem might have begun when Cox downgraded me from the Panoramic 4331 router (one of the white ones) to the 4141 (older black ones). Cox even swapped out the 4141 for another 4141 but the problem still occurs.
I show Call Waiting ON after a reboot. It seems independent of the cable modem hardware. I think it is a much more systemic problem that many have problems with but COX has no desire to address. Nice to know there are others struggling with similar issues but that does little to solve the problem.
