Comcast Approved Telephony modems

Telephony modems are currently speed limited and do not support extreme and Gigabit Speeds. You will need to purchase two modems if you have both telephony service and Gigabit 1000 Mbps service. For 250/300 Mbps, NETGEAR CM500V works well and for 400 Mbps services you will need NETGEAR C7100V or ARRIS SVG2482AC.
