Abstract

In the last few years, multimedia communications has been developed and improved rapidly in order to enable users to communicate between each other over the internet. In general, the multimedia techniques consist of instant messages, audio, and video chatting services. However, users cannot phonetically communicate with each other unless they use the same chatting applications since each chatting application has its own control protocol to handle the call setup, the real time media transmission, and the call teardown sessions. The only way to enable the users to communicate phonetically using different chatting applications is to design a new architecture by proposing an interworking module between the control protocols used by the applications. The interworking module between at least two different protocols is a very critical issue as it solves the data transmission problems when using different chatting applications to create a voice call, and demonstrates that the voice conferencing between heterogeneous control protocols identifies the interest of combining the features and taking the advantages of more than one protocol in a single network. The two chosen protocols in this paper are: Inter-Asterisk exchange Protocol and the extension of extensible Messaging and Presence Protocol. Each protocol differs from the other one in many terms. Thus, this paper clarified the main differences between IAX Protocol and Jingle Protocol by doing a comparison in terms of registration, URI format, signals, transport methods, audio and control packets, bandwidth, scalability, functionality, services, etc. This comparison is due to define the common and the unique features to ease proposing the IAX-Jingle mapping architecture, signaling and media transfer modules. So, people around the world will be enabled to talk with each other without caring whether they are IAX or Jingle users.
