Hello Everyone,
I must deploy an asterisk system that can support
at least 500 pstn outbound calls.
It's a challenge as it's the first time i'm gonna build such a
large
system.
I want to have your advice on hardware, software and so on . What i have in
my plan is a cluster of servers with quad PRI cards.
I will appreciate your advice.
Thank you all .

Different people have different opinions. My personal preference, if this is United States: DS3 -> Adtran channel bank, break out PRIs PRIs -> multiple Cisco PRI->SIP appliances. A 3845 maxed out can do 24 PRIs. I recommend using two and splitting load for capacity / failover. Using pure SIP between the gateway appliances and at least two asterisk boxes for flexibility and failover-ability.

AudioCodes also has equipment that can support a DS3 connection, or multiple T1s directly to SIP. For example, If you are getting 22 T1s then get two AudioCodes Mediant 2000s with 16 spans (maxed out) or two Mediant 3000s with 21 spans. If you are getting a DS3, get a Mediant 3000. The M3000 supports up to 84 T1s or three DS3 or one OC3. Then leave call management up to Asterisk. Of course, have redundancy everywhere you can. -Jonathan
