Important:
If you install the X5v where your phone line enters your home, be sure to connect an answering machine between the X5v and the demarcation point. If you don’t, and someone calls you over the regular phone network while you are on a VoIP call, the call will not go through. No phone will ring at your end. If you attach an answering machine to the X5v, regular phone callers can leave a message if you are on a VoIP call.
