Abstract
A first device uses a PSTN to send its public IP address to a second device to setup point-to-point communication over the Internet. The first device calls the second device over the PSTN. In one embodiment, the second device answers the call and the first device transmits its public IP address over the connected call to the second device. In another embodiment, the second device does not answer and the PSTN transmits the public IP address as signals in several intervals between telephone rings to the second device. The second device then sends a connection request to the first device over the Internet using the IP address. Once the connection over the Internet has been established, the first and the second devices point-to-point exchange data packets carrying text, voice, video, or data communications between their users.
