Which new Comcast Modem/Router

[sirrylanodory]

Hello, recently my internet has been going down randomly throughout the day, ping spikes etc etc. comcast says my internet is fine etc etc. so i thought its about time i get rid of the XB3 modem/router for an actual modem router like the

ARRIS SURFboard SB6183
with
NETGEAR RangeMax Wireless Router WNR1000-100NAS

these are on the "approved" list, but what i'm not understanding is the Comcast Voice part; will these two work with Comcast Voice? or do i need to find a modem/router that supports voice?
