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
board,
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
24/7...
