[asterisk-biz] Large System

[William Boehlke]

At 1,000 registrations you should use another SIP registrar such as SER or
break up the dial plan.

If it's a business system you should plan for 300 concurrent calls. We would
put that on two PC servers with a third or fourth for conferencing and
failover.

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.
Mike
