I know. :)
I've already mentioned some of the OpenSIPS options to him on the
OpenSIPS users list (LCR module specifically). Just brain dumping
everything that came to mind.

OpenSIPS/Kamailio have modules designed specifically for that kind of
functionality now without a need for an outside monitoring process or
SRV reliance.

One other thing you could try would be to use OpenSIPS and use a
standard config that routes to a hostname (with a creative failure
route
setup). You'd then setup the hostname in DNS as multiple SRV records
reflecting your pool of Asterisk servers (set your TTL very low for
these records). You could have something like sipsak send test
messages
every 30 seconds or so to each of the Asterisk servers. If one quits
responding, then the monitoring app updates your DNS servers removing
the effected Asterisk server from the DNS pool and effectively from
the
usable gateway pool.
I actually wrote one of these ages ago that worked fairly well with
a10
calls per second SER server. How many calls per second are you
looking
to process?

Hi all,
I've googled around for concrete solutions on load balancing
Asterisk,
and it appears there are several ways to skin this cat -- but not
one
solution which is all appealing. I have the following requirements,
which aren't anything extraordinary:
* I need to handle roughly 300 simultaneous phone calls to start
* Eventually scale to 1000 simultaneous phone calls
* I want to be able to pull out an entire server from the cluster
without affecting my application
* I'm doing all my trunking over SIP
So far I've seen folks mention the use of DUNDi and OpenSER(Now
OpenSIPS), but unfortunately the documentation out there is rather
sparse and lacks detail for someone who isn't extremely keen with
the
intricate details of Asterisk or OpenSIPS.
Would anyone be able to suggest a good starting point in as far as
reading documentation and testing out some solutions? I'd also be up
for hiring a consultant to help me get started -- but I believe the
proper forum for that is asterisk-biz. (Which I've already posted
to).
Thank you for your insight on load balancing Asterisk.
