[Serusers] Questions about SER+SERWEB+SEMS deployment

[matt morris]

Thank you Greger for your previous reply.

Few days ago I just finished installing SER 0.8.14 and serweb stable with 
mysql authentication and accounting. Seems to be working well. I'm moving my 
focus to SER 0.9.0 with "centralized" Radius accounting and SEMS (if 
possible). I still have several deployment questions about that though.

For the "fifo_db_url" parameter in 0.9.0, what feature(s) does it enable?

About RADIUS accounting, several users posted their problem in not being 
able to run the RADIUS server on a different host, but seems there were no 
answers to their inquiries. Is that true?

For SEMS, Greger mentioned that it "uses a full ser instance as its 
front-end". Does it mean that it can be run on a different host so it can 
serve as a "centralized" media server for several different SER proxies? I 
planning to test out an announcement feature - users need to hear an audio 
before their call will be established with the callee. Somewhere in the list 
I saw people said that this can only be accomplished with the use of a 
B2BUA. While SER+SEMS have an announcement feature, is it a different 
feature than "Pre-call speech", or SEMS cannot be run as a centralized media 
server for such purpose without some re-programming?
