I have Xfinity and am interested in xFi. I own my own telephony modem and router and do not want to rent from Comcast. According to Comcast's website, the only xFi compatible equipment would be the Arris 1682G, Cisco 3941T or Arris TG3482G. I am wondering if anyone knows if these are all Voice/Telephony compatible and which is the "best" of the three. Thanks for any information.
