Looking for Cable Modem that supports 1 GB/s speeds and voice.

[Jelloman]

I am looking for a baseline cable modem that supports 1gb/s and voice. Best i could find is the NETGEAR Nighthawk AC1900 with voice. But its a bit pricy when i already have a standalone router. Any info would be great. ISP is Mediacom in Iowa for compatibility.

Thank you.

That is the only modem we have that supports voice at the moment.
