  Hi

   

  A session is more than just user information and user authentication, although that is a big part of it.

  A session remembers where data is to be sent and what state the stream is in. Ofcourse it remembers the location and some details of the receiver(s) and it controls the path of the streams.

  The existing session, created with SIP, is used when a stream is paused or stopped. All not-media data (control data) is sent using the existing session. Without session, no terminal would know where to send its data, or to send what type of data.

   

  So you cant make a call without a session. You can make a call without user authentication. And you can also make a call without a SIP session.

   

  Hope this helps..

  Rudie

    Hi friends,

    What is the use of creating session using SIP...Just to know ONLY user information are we using Session?

    Even without Session i hope we can do a call,send message by using necessary protocol(because no where we are using SIP for doing call..)... 

    Are we using session just to validate User?..If there is any other reason please let me know,or else if you have any link please forward it to me ...it will be helpful for me..
