A method for providing a videoconferencing service between two fourth generation wireless terminal types including cellular or wireless mobile and fixed terminals, said fixed terminals to include television receivers with a 4G wireless interface, each terminal employing a video camera, a microphone and loudspeaker. All terminal types will be rendered parametrically compatible by use of subscriber tables which identify called terminal parameters and which contain a class of service sequence which identifies the originating terminal's parameters wherein said class of service sequence is sent to the receiving terminal in an alternate caller ID along with selection characters which cause direct routing to the receiving terminal. The called subscriber may opt out of a video send mode by sending a “canned” video frame advising the caller that video is not available.
