<font size="-1"><font face="Arial">Hi all,<br>
<br>
I'm designing a new VoIP platform in which transcoding and
prepaid features must be provided.<br>
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 media services. <br>
What is the best practice in this case? I could design the
architecture in two ways:<br>
<br>
1)<br>
Users Providers/PSTN<br>
|| ||<br>
Opensips/Mediaproxy <==> B2BUA<br>
<br>
(here opensips/mediaproxy+B2BUA acts as a whole SBC)<br>
<br>
2)<br>
</font></font><font size="-1"><font face="Arial"> Users
Providers/PSTN<br>
|| ||<br>
B2BUA<br>
||<br>
Opensips/Mediaproxy<br>
<br>
(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)<br>
<br>
<br>
If I use a b2bua for all sessions, do I still require a media
proxy for nat traversal?<br>
<br>
Thanks for your hints.<br>
<br>
Best Regards,<br>
