I know there are a couple companies out there with 1000+ phones on
solely asterisk systems. We're in the process of rolling up from testing
into about 1700 phones this summer (a few hundred in the next week, then
a straight shot from there to 1700 by june), and then up into the
8000-10000 phone range by next summer, replacing an old nortel meridian
system. We've found that asterisk is more than capable of handling the
call load, as long as you've got the dialplan and database's programmed
right.
There are quite a few ways to make it redundant. Dundi's a good way to
set up multiple distributed locations with support for automatic extension
detection from other servers, or you can program the cluster capabilities
into the dialplan and rely on DNS to get the phones to the right server.
We're currently looking at 2 primary call servers (separate gateways and
voicemail servers) to handle all the calls, if need be we'll drop in
another one and add it to the cluster to handle more call load.
Best of luck :)

Does anyone know of an Asterisk system with 1000 SIP phones? I'm being asked
to propose an alternative to Cisco/Avaya/Nortel pricing, but I've never
contemplated a system this large.
Should I consider a SER front end (to register the phones and for
inter-company calling) with an Asterisk back end (to provide the PSTN
interface)? Or would an Asterisk system handle 1000 phones? Ignoring
conference bridges, how should the system be sized?
Until now, I've ignored the Linux clustering discussions on the list. Should
I consider a monolithic server or a distributed system with each server
having ~250 phones and a PSTN interface?
The real scary part of this project is the necessity to upgrade the wiring
(both Cat3 and Cat5) in a very old (lath and plaster) building. I've observed
two-prong (no ground) electrical plugs, so I'm thinking a PoE phone with PC
jack at each work location. Or maybe a NetJack at each location.
Thanks for your advice.
