I plan on purchasing a cable modem and would like it to be compatible with Cox Voice. Do I have any options?
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.
they don't give out the 3212 any longer
Oh, thanks for the tip.
