[Asterisk-biz] Asterisk w/ Quad Cards

[Alistair Cunningham]

It's not Asterisk, but I've done clusters of 6 telephony machines each 
with 4 IBM DTXA cards, each card with 4 T1s, giving 23 * 4 * 4 * 6 = 
2208 channels per cluster. The machines connected to a shared (and 
highly redundant) database and file store. The machines were IBM pSeries 
p630s and p660s, and the software was IBM Websphere Voice Response.

If you design your system properly, you can do a similar thing with 
Asterisk on a smaller scale. Use one quad PRI card per telephony 
machine, talking to a shared database. The telephony part is pretty much 
infinitely scalable; the limiting factor is how big a database server 
you can build.
