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...
