I did something almost exactly like this for a client about 5 years ago,
but we used 1 te410p in each pizza box with the 4 PRI's in an NFAS group.

I "screen" each incoming call so I can discard [unwanted|abusive] callers
on the "telco servers" before I hand off to the "application servers."

I'd take a slightly different tack. I wouldn't start with the samples. I'd
start with empty files and copy the bare minimum from the sample files
until it works and then I would:
) Add access control features to [iax|sip].conf
) Only log to a central log host via syslog so you can [analyze|ignore]
everything at once. My /etc/syslog.conf only has a single line: "*.*
@loghost" Also, you reduce disk I/O and space consumption.
I do use the sample indications.conf because I've never taken the time to
figure out what I really need.
"Building up" the conf files helps you understand exactly what you are
doing and why. Also, as any good mechanic will tell you, parts left out
don't get broke.
This is most of my extensions.conf:
[globals]
HOSTNAME = ${ENV(HOSTNAME)}
SERVER =
iax2/${HOSTNAME}:${[email protected]
; all calls start here
[block-ani]
exten = _x.,1, verbose(1,[${CONTEXT}:${EXTEN}])
exten = _x.,n, answer()
exten = _x.,n, set(DNIS=${EXTEN})
; update the channel status in the database
exten = _x.,n,
agi(update-channel-status,--offhook,--debug,--verbose)
; see if this ANI should be blocked
exten = _x.,n, agi(block-ani)
exten = _x.,n, goto(${STATUS},1)
; hand off to the application server
exten = SUCCESS,1 dial(${SERVER}/${DNIS})
exten = SUCCESS,n, hangup()
; hangup
exten = FAILURE,1, playback(redirect)
exten = FAILURE,n, hangup()
The AGIs are written in C so the performance "hit" is a very small
fraction of that of AGIs written in Perl or PHP.
