asterisk users - Dec 2007 - How does Asterisk scale to 500-1000 phones?

Anyone have opinions on how well Asterisk scales to 500-1000 stations, in
regards to reliability, system performance, as well as ease of management?

Assume relatively low call volume; let's say two public network PRIs (47
DS0s).

Jesse,

We have multiple installations of this scale and a few with far more  
concurrent call paths (250+).  In our experience, Asterisk scales  
nicely to these levels as long as you are realistic about what you  
expect of the server.  For instance, we rarely, if ever, convert  
signal to TDM.  We instead use SIP dial tone from a tier-1 carrier.   
Also, if you expect any substantial amount of meetme conferences, you  
might want to consider running those on separate hardware.  As the  
numbers go up, you can peel-apart your switch into functional duties  
such as two SIP switching servers, two voicemail servers, one  
conferencing server, etc.

Just some ideas.  Best of luck to you!
