We use ulaw (for the logarithm mode of the volume) so no recoding is done...
each board fires 2 irqs and 1000 irq/sec each... so is 2000 irq per
at a max of 6000 irq /sec....
Cpu use (using top) is about 10% only when receiving fax (because of
the spandsp), goes to 20%... when recieving 4 simultaneous fax....
We use Hylafax + iaxmodem... works like a charm... the same way
