Quite this kind of setup, a little bit more complicated, as I have a few 
media servers, and other things on my voip cloud...

To simplify, I have more something like that ( even it's not quite 
accurate ):

External UA's ---> FS --> Oser --> FS --> PSTN.
                                           ||
                                  Internal UA's

Openser for internal users, fs for externals.

Openser is really better if you intend to have a lot of UA's registered.

dispatcher and dns.

PBX features are managed in fs with prefix added to numbers for features 
(for example: interception is int{thenumbertointercept} ).

both to provide redundancy of information.

nat is handled by FS using different profiles, I don't want to deal with 
real NAT situations ( although I had with Oser and mediaproxy )
I don't have prepaid applications, we're a call center telco provider, 
but you can handle these with Oser Or freeswitch, look at mod_python or 
mod_lua :)

just a set of sofia profiles for freeswitch and a good routing config 
for OSER should do the trick, there's nothing complicated, contact me on 
irc if you need :)
