A TV receives IP calls and POTS calls. When a POTS call is received the TV passively passes the call to a non-IP phone, and when an IP call is received the TV processes the IP packets as appropriate for the non-IP phone and passes the call to the phone. The non-IP phone can also signal using a special code a desired to place an IP call, with the signals from the phone being rendered into IP packets by the TV. In this way, a non-IP phone may be used to place and receive both POTS calls and IP-based calls.
