I plan on purchasing a cable modem and would like it to be compatible with Cox Voice. Do I have any options?
You can't purchase a modem that will support Cox voice. You can get those from Cox via rental or the one for phone only for free
What data plan are you on? You can either get the Cisco DPQ3212 or the Arris TM3402. The TM3402 is if you have Gigablast. They are both a free lease from Cox.
If you want a phone modem with a built in wifi router, then you can also rent the Technicolor CGM4141. Not sure how much, but there is a monthly charge with no option to buy. I would suggest buying your own router, but to each their own.
You can, but Cox will not authorize customer owned phone modems
they don't give out the 3212 any longer
Oh, thanks for the tip.
