I just purchased a ARRIS SURFboard SBG7580AC 32x8 DOCSIS 3.0 Cable Modem/AC1750 Wi-Fi Router and found that it doesn't have a telephone jack. What do I need to continue using Cox telephone services? All help is appreciated.
cox unlike other companies does not allow customers to own the phone modem, the rent the basic non router version for free while they also also offer a combo modem wifi router that is rented fromcox for a fee
