The main gain in using a B2BUA is that you take responsibility for
terminating the extra call legs, it is as good as your B2BUA will be, by
delegating the responsibility upstream you can not always be sure it is
handled properly.
I wonder if Kamailio should consider evolving in B2BUA support.
I am expecting to receive tomatoes.

Hi Alex,
Isn't the option of generating multiple call legs with a B2BUA more
subject to dead air/ghost calls than letting kamailio handle parallel
forking?

It should be noted at a rather general level that
parallel forking is
replete with race conditions, and is a nasty and unwieldy aspect of SIP.
The pain of using parallel forking to implement something like "ring
groups", for example, is often not worth the savings in architectural
complexity.
If you have some other means of accomplishing what you want to
accomplish, e.g. using a B2BUA to generate multiple independent call
legs simultaneously ringing multiple destinations, I strongly advise you
to go with that instead.
