Our phone jack is not near our modem, but it is in the same room. Can I still use Xfinity Voice?
Yes. You can:
Base wire fm modem/Tel 1 to wall jack, OK. Other house phones OK voice and ring in and out. But . . .
Bell touchtone deskset (see pic), into modem/Tel2, rings on incoming and can complete outgoing calls, but when phone rings and receiver is lifted, incoming call is disconnected regardless how many rings have elapsed.
