Abstract

In a communications system, after parties form a voice telephone connection, the parties respective communications devices automatically create or leverage machine readable features or content of the telephone connection to identify the parties to each other or to a rendezvous server, and thereafter the communications devices and/or the rendezvous server automatically establishes a data link between the parties.

sending data destined for the remote party to the rendezvous server over the digital data link; and

receiving data from the remote party via the rendezvous server over the digital data link.

6. The communications apparatus of claim 5, further comprising:

exchanging multimedia content representing human-readable communications between the local party and the remote party over the digital data link.

7. The communications apparatus of claim 1, wherein analyzing the sound signal as captured through the microphone corresponding to the local party and the incoming acoustic signal captured through the remote microphone from the remote party includes:

performing a computational analysis of data captured by the microphone to identify a phone number dialed.

8. The communications apparatus of claim 5, further comprising:

receiving an IP address from the rendezvous server; and

establishing a digital data link over the data interface with the remote party using the IP address received from the rendezvous server.

9. The communications apparatus of claim 8, further comprising:

exchanging multimedia content representing human-readable communications between the local party and the remote party over the digital data link.

10. The communications apparatus of claim 1, wherein the established telephone connection includes a conversation between the local party and the remote party, and wherein analyzing the sound signal as captured through the microphone corresponding to the local party and the incoming acoustic signal captured through the remote microphone from the remote party includes analyzing the conversation to identify the telephone connection, wherein the conversation includes both the sound signal as captured through the local microphone and the incoming acoustic signal as captured through the remote microphone from the remote party.

11. A computer implemented method to establish a data link between parties, each party having a computer and a telephone, the method comprising:

establishing a telephone connection between the parties over a public telephone network either directly or via a conference calling bridge;

connecting the computers to a prescribed packet data network and automatically acquiring addresses on the prescribed packet data network;

capturing a sound signal through a microphone corresponding to a local party of the parties and capturing an incoming acoustic signal through a remote microphone corresponding to a remote party of the parties;

computationally analyzing the sound signal as captured through the microphone corresponding to the local party and the incoming acoustic signal as captured through the remote microphone corresponding to the remote party, to identify the telephone connection at any of the computers or a rendezvous server;
