[Freeswitch-users] Speccing server for enterprise FS

[Alex]

Looking to setup a new Freeswitch server that will be doing quite a lot 
of traffic.

Trying to get a rough idea of where to spend the money (RAM? CPU? 
Network access?).

There will be perhaps 10,000 simultaneous SIP registrations
Maybe 500 simultaneous calls, some of (say 50%) which will require a-law 
to GSM transcoding.

I know it's a tricky one to answer, but based on experiences here, which 
bits tend to glow first?
