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.

What is claimed is: 
     
         1 . A method of RTP streaming using circular buffers for a VoIP client embedded in a Web browser to implement a peer to peer VoIP call based on a SIP environment, comprising:
 placing a plurality of incoming packets from said RTP streaming in said buffer while a plurality of audio packets are read concurrently while in a plurality of buckets in said buffer;   holding one said audio packet in one said bucket from said RTP streaming, while each said incoming packet is assigned to a said bucket;   having a playback thread reading said incoming packets said bucket by said bucket by incrementing a read index to arrange said incoming packets into said buckets in a correct sequential order; and   having a network thread writing said audio packets into said buckets in said correct sequential order.
