Steven,

Thanks for the response. We have a broadband customer base of 30,000 that we would like to offer VoIP services. We plan to use dual 3.0Ghz Xenon CPUs
with 1GB dual DDR 400Mhz RAMs. Each server will have 8 PRIs and connected at 100Mbps to the outside world. We will support only SIP devices. We think we can support about 2,000 to 3,000 customers on each server. If that is the case we will need about 10 Asterisk servers. The question is how do we link up these servers and allow any user come in on any servers?

Have anyone tried this?

Oliver
