Switching between communication systems with circuit and packet switching |
摘要 |
A call jump establishes a jump from a call of a traditional telephone carrier established with audio signals. When it is determined that video should be added to the call, a packetized network is connected. The audio and video are transmitted over the packetized network. There is provided standard telephone equipment. A video enabled device is capable of rerouting the audio selectively to either the traditional telephone carrier or the packetized network. A packetizer packetizes the audio signals from the standard telephone equipment and the video. <IMAGE>
