Claim:
A firewall-tolerant Voice-over-Internet-Protocol (VoIP) system comprising: a VoIP client that receives local audio captured from a local user, and plays back remote audio from a remote user, the VoIP client comprising: a sending thread that receives the local audio and generates a hyper-text transfer protocol HTTP GET message that contains an audio cookie, the local audio being embedded in the audio cookie for transport over an Internet; wherein the audio cookie is an HTTP cookie field specified by an HTTP protocol to contain user data that is generated by a server and stored on a client, but specified to be sent to the server when the client later re-connects with the server; wherein the HTTP GET message is a message specified to be used to request data from a server; a receiving thread that receives an HTTP response message from a server on the Internet, the HTTP response message containing a data field that contains the remote audio from the remote user, the receiving thread reading the data field to extract the remote audio for playback to the local user; whereby local audio is transported to the server in the audio cookie that uses the HTTP cookie field specified to be used for transferring user data generated by the server.
