Hello, Here is a question which I have for long time. What is the prupose of having B2BUA? I know that the B2BUA changes from tag, callid and maintains a seperate dialog when to tag is received.
But why it does change in these headers? Some say it is for security reasons? If yes how is it used for security. We also have NAT for security. Some say it is for manipulation of supplementary services. If yes, cant a statefull proxy handle the services without changing call-id, from tag and to tag?
