SIP Is the Next Step of VoIP Development

Note that the H.323 specification is oriented towards the use of “stupid” terminals, and all management functions and services are performed on central servers. At the first stages of the development of VoIP systems, this feature was perceived quite naturally, because of they, in fact, were the successors of conventional telephone services. But you will agree that in the Internet age such architecture already seems archaic. After all, there is no place for such a variety of opportunities to increase the functions and services that the World Wide Web provides today. And as the time dictates a new model for building VoIP systems, based on the open protocol Session Initiation Protocol (SIP) and Java.
