 What do I need to hook my telephone up to this router?

A different modem/router/voice device?
Or a voip device/service like ooma?
The C6900 is a modem/router only device. It doesn't have voice. So you'd either need a different modem/router that has voice or need to go with a voip service not through your isp.
