Jiri,
Thanks for your prompt response.
We want to implement a pre-paid system in which once subscriber's balance is depleted,
the dialog could be torn in time. However other Proxy or other elements could not take
part in the call, they could not send a BYE to caller directly. It's the why we
consider B2BUA.
We project to build a B2BUA to support voice/video/IM at first stage, and support other
SIP based services as they emerged.
However, I just noticed the definition of B2BUA in 2543-bis04 in several sentences, there
has no other analysis on performance, reliability, limitations and how to implement it.
So, I hope to get help from the society.
Thanks for your help again.

Hello,
ser is not a B2BUA -- it can act as proxy, redirect, transactional UAS
or registrar. These modes make a vast majority of network scenarios
happy without a need to use a B2BUA. Which is good, because B2BUAs
inherently have certain scalability, reliability and security limitations.
Is there a particular reason why you would like to use a B2BUA?

Hi All,
I am newbie of this field, thanks everyone help me.
I am interesting in B2BUA, however, except some brief defination in 3261, I could not find
any further defination or how to implement about B2BUA, I noticed that SER could be
implemented as a B2BUA, where can I find some implementation? or where can I get any
description?
