I am currently have Comcast for my telephone service and fast internet access and equipped with an ARRIS TM602G. I am thinking to upgrade it to a modem sod from Walmart: "OBi202 VoIP Telephone Adapter with 2 Phone Ports, Router and USB" (web link: http://www.walmart.com/ip/OBi202-VoIP-Telephone-Adapter-with-2-Phone-Ports-Router-and-USB/26509538#Q%26A+Exchange). My question is will this modem work for me (both telephone voice and internet access)?
Many thanks!
