“Is this device compatible with Comcast voice phone calling?”

1-2 of 2 Answers

• This nighthawk modem doesn't have a phone jack. We have Cox digital phone service and we had to keep the older modem connected to keep using the phone service. The two are connected without any network issues. We use a splitter to connect the two modems.
