CPU is the limiting factor, but on recent hardware you should be able to 
do 120 channels or more simultaneously, without it having to be really 
high end hardware.

We have a test tool in the lab, similar to the show codec translations 
on asterisk, to estimate how many channels you could do, i will have it 
added to the attrafax archive in the coming week so that you can 
estimate things easier.

To already give you some idea in the mean time, when we ran the test a 
long time ago on our very old single core p4 based xeon 3.06 ghz ( 
http://www.cpubenchmark.net/cpu_lookup.php?cpu=Intel+Xeon+3.06GHz ) we 
could do about 40 simultaneous channels.

Ratings on recent cpu's such as the core i7 have a rating on the same 
website that is about 15 times higher, so i would presume that 120 
channels would be handled easily.
