pose some interesting questions. As a quick and dirty estimate if you
assume one of the standard small ec2 instances could cope with 100
simultaneous g711 calls (I don't know if that is the case just
guessing) then you'll chew up approx. 2MB/s (you pay for bandwidth
both ways). Assuming that you'd then have 1MB/s average to account for
quite and busy call times then it would be 3.6GB/hour or 86.4GB/day.
At the Amazon price of $0.10/GB that's $8.64/day or $260/month. The
server instance will cost you $72/month so total cost for 100/calls
per month is $332.

A typical dedicated server for $300/month is roughly equivalent to an
ec2 small instance and comes with 500GB of bandwidth/month which is
only a fifth of what's required but you could probably get the extra
2TB/month thrown in for $32/month making the dedicated server and ec2
prices the same.

There are serious pros and cons between these approaches. With the ec2
you don't get a permanent static IP, with a dedicated server you do.
With ec2 you could scale up and down between 1 server and 4 servers at
the drop of a hat to save costs and cope with peak and quite times,
with dedicated servers you're stuff with 12 or 24 month contracts for
the number of servers you'd need under maximum load. And then of
course the major factor for both is what the call quality will be
like.
