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?

Dear Matt,
A small group of ser users have started to write a Getting Started document
that will address many of your questions. A date for a first draft is not
yet set, but the draft will be posted to this list.

I'm a new user of SER. Just some questions
about how I could deploy
SER+SERWEB+SEMS, possibly on separate hosts, as I plan to have more
than one SER proxy server with a centralized web server and
media/voice mail server (1) Basically what features will I be missing
if I decide to omit the fifo functions (if possible) in serweb? (
aliases, add new contact SIP address and who are online would be
three features, right?)
Standard ser does not have network-based FIFO functionality. Various
initiatives have worked on this issue. Meanwhile, my advice is: Do not
start with this complexity. Use FIFO (only thing serweb supports today),
install serweb on the same server as ser, get it up and running and start
the learning curve.
(2) I saw in one of the threads that there is a
fifo_server.php file
available for fifo-Internet relay, but not quite sure how to use it.
Could someone give me some pointers?
cvs 0.9.0 in the utils directory.
(3) Somewhere in the mailing list I saw the
"fifo_db_url" global
declaration, is it a feature only available in version 0.9.0? And is
there a serweb version that will work with ser 0.9.0?
Yes. And no, I believe serweb is not yet fully functional with 0.9.0.
(4) I have not tried SEMS yet, but since it also
communicates with
SER via fifo, I would assume it has to be in the same host as SER,
right? Are there any existing modules/plugins that will allow SER and
SEMS on different hosts? If not, would it be more scalable if I build
an Asterisk box to handle voice mails?
No, sems uses a full ser instance as its front-end. See examples supplied.
There are different opinions as to whether sems is mature enough to handle
voicemail. It depends on your needs. In the Getting Started doc we will use
Asterisk.
(5) If I have multiple SER proxy servers on
different hosts, how
could UA Alpha registered with SER proxy A be able to call UA beta
which registered with SER proxy B? What setup/configuration would I
need?
There are no short-cuts to accomplishing what you want. You need to fully
understand how proxying and other things work. Start out with a tutorial,
read the admin manual, and go through the serusers list on mail.iptel.org.
