I would recommend breaking apart your SIP switching from your
voicemail, conferencing and other advanced apps in an install of that
size. Asterisk Business Edition on a high-end 2970 or so could handle
that many seats in one server, but would not scale to the customer's
request.
Consider a three server design. 1 OpenSER SIP switch, 1 Asterisk
Voicemail and Conferencing unit and 1 CDR aggregation, call recording
and reporting platform.

I'm going to be working on a VoIP PBX RFP. The requestor is looking
for approximately 550 handsets to start with and would like to be
able to scale up to 10k handsets (I can't imagine how they'd be
using 10k of them, but they ask). I'm guessing maybe 2x PRIs worth
of traffic externally, couldn't be much more than that internally.
Of course scalability here is desired if they want to know how to
scale to 10k handsets.
I'm looking for suggestions on the PBX itself. I can take care of
the handsets (I'm Polycom certified) and the PSTN.
