Hi

 

Can somebody tell me the difference between Dialog and session and
transaction?

 

First let me tell you what I thought it was.

 

If there is a UAC and UAS, If UAC sends a request and gets a non-100
response back the whole process is knows as a dialog

And from the point of first request to the ACK sent for BYE it is  a
session. 

 

Now if what I have said above is right then how would you differentiate a
request sent outside the dialog? As in doesn't that also get a response back
could that not be a non-100 response?

 

Can Someone help me get this confusion cleared?

 

Thanks again

 

Ganesh
