Make your tools make sense

 Learn about the equipment you need to keep your home phone service running strong.  

Phone headset

To use all your Cox Voice features, make sure your handset supports DECT 6.0 and features like Call waiting. DECT 6.0 comes with tons of perks, like:

Saving power

DECT 6.0 gives you more range without using more power, so it’s as good on calls as it is on costs.  

HD sound

Hear your friends like they’re in the same room, even from across the country.  

Wiretap protection

Chat with friends, knowing no one else is listening.  

Better range

Take your calls to new places with better range on the latest phone system.

Zero network interference

No interference means no interruptions and no more of that awful buzzing noise.  

All-in-one modem

To use Cox Voice, you’ll need an eDVA, which is an all-in-one Wifi modem and phone adapter. Don’t worry, we’ll give you one when you sign up.  

No power? No problem.

If there’s an outage, just stick a battery in your modem to use your phone and e911 service.

Cox voice equipment FAQs

You can install the batteries yourself, or you may have the option of having a Cox technician install the batteries for you. Professional installation is available at checkout.

It's smart to check the battery status of your telephone equipment on a regular basis. There's a battery indicator light on the front of your modem. You can see what the light is saying about your battery here.

Backup batteries can provide up to eight hours of standby service or up to four hours of talk time using a corded telephone that doesn't need power and is directly connected to the modem's jack.

You can buy batteries when you first sign up for Cox Voice or anytime at one of our retail locations.

In an outage, your corded phone will work using your backup battery, but cordless phones require an additional power source, which is why we recommend keeping a corded phone around to use whenever you lose power. Also, make sure you keep non-emergency calls to a minimum during a power outage to prolong the life of your battery. Get more information here.
