We've considered this, and we only let each number be called once, this
is obviously not perfect, which is why we don't allow free email
accounts to sign up, again not perfect but each layer helps. We also
introduced a 15 minute delay, with no other calls to be queued at the
same time, this is to reduce the instant gratification in having someone
pranked and also limit the number of calls each account can make, at the
end of the day people using FWD to make free calls in the US would get a
better buzz then trying to abuse our system...
To unlock a number people have to email us...

This is like asking how long a piece of string is, it's as long as the
sum of 2 halves... How much per meg are you paying...

Depends how much you pay per meg...
Also have you thought about using a provider that offers DoV?
However even at Telstra rates of 18 and 19c per meg, it's about 400
seconds for 1Meg of data at 2.5kBytes/second, or 6.6minutes for the cost
of a local call...

Can't comment in general I haven't done enough testing to conclusively
say however testing between myself and a friend using GSM and SIP,
friend was using a SIP client over the internet to my asterisk server on
the gateway of my LAN was averaging between 2.2 to 2.5kBytes/second...
