I'm designing a new VoIP platform in which transcoding and prepaid
features must be provided.
One essential component of the architecture will be a b2bua, but I'm
wondering about where it should be deployed. In detail, I'm thinking
about a "standard" architecture (opensips + mediaproxy) with a b2bua
(freeswitch) used for media transcoding, prepaid, topology hiding and
What is the best practice in this case? I could design the architecture
in two ways:
Opensips/Mediaproxy <==> B2BUA
(here opensips/mediaproxy+B2BUA acts as a whole SBC)
(here the B2BUA should works also as SBC and could do
protocol interworking (es h323) but which component should
authenticate/authorize the users? I would like to handle all subscribers
just in opensips)
If I use a b2bua for all sessions, do I still require a media proxy for
Thanks for your hints.
