    You will need to use Cox's voice modem for telephone service. You can use your OWN modem for Internet, which is what I do, I have a Cox DPC3212 modem for telephone service and I use my personal DG2460 modem for Internet, though I will be upgrading soon.

Just to focus in on what Darkatt said, you can't buy your own voice modem (eMTA) with Cox. They provide you one as a free lease and uses coax. The latest one is the TM3402. FYI you can use a virtual client with their Cox Business Voicemanager, but that is probably beyond what you are trying to do.
