[asterisk-biz] Creating a monster...

[Mitul Limbani]

Hello,

I woud recommend using quad red fone devices over 1gbps Ethernet, all  
on 1U servers with dual NICs and since there is no on machine irq  
used, you can do away with lesser powerful boxes.

You can also look at HA with ultramonkey heartbeat, to ensure  
avolability in mission critical situations.

If you need any setup n confg help we can provide the same.

Thanks & Regards,
