INSTANT INTERNET BROWSER BASED VoIP SYSTEM

Abstract

The present invention is an instant Internet browser based VoIP system with a VoIP client in the form of temporary VoIP applets that can start in a Web browser and can establish an instant peer-to-peer connection with another web-based or hardware embedded/installed VoIP client using session initiation protocol (SIP) and real-time transport protocol (RTP) audio streaming. The applet is a small file that is easily loaded onto a user's browser and uses application program interfaces (APIs) that require no additional libraries. The applet is written in JAVA, although other programming languages may also be used to write the applet.

1 . A method of performing a firewall strategy in a VoIP client embedded in a Web browser to implement a peer to peer VoIP call based on a SIP environment and RTP audio streams, comprising:
 initiating a VoIP call;   initializing said VoIP call through a controlled relay connection;   determining what type of firewalls exist in said SIP environment;   determining a set of IP addresses to establish caller contact;   establishing and confirming said peer to peer connection and dropping said relay connection; and   utilizing a plurality of codecs to compress bandwidth to allow continuation of said VoIP call.
