Well, the number of users doesn't say much about how many simultaneous
phone calls you're going to process. That's the important
factor here. As you see from other replies, one asterisk box will
never be able to handle the amount of calls, even though it could
handle 5.000 registrations. You need to find a way to scale, and
different people have different opinions about it.
I focus on the SIP protocol and scale by using a SIP proxy in front of
Asterisk. Other people focus more on Asterisk itself and build
scalability with
database clusters and Asterisk's own protocol called Dundi. There are
many ways and much advice to be found if you
search the web and the mailing lists.
Before you go any further, find out some important facts
- How many simultaneous calls? At which hours?
- Any need for monitoring, conferencing or other CPU-intensive voice
applications?
- Do you need NAT support for the devices?
- Will every user only have one phone or multiple phones?
There are plenty of people on the list who work as consultants with
this kind of setup, and as Alastair said, looking at it from an
service provider background this is a fairly small platform.
Currently, I'm involved in a project that starts with 50.000 users.
This means that you won't explore uncharted waters, the solutions for
your problem exists out there and has been in use for a long time.
