[Asterisk-Users] rxfax problem

[Mohammad Shokuie]

Hi Steve,

As a matter of fact, you've done a greate job in writting this library, no 
doubts. I really dont know rxgain = 12 makes that much distortion but I'm 
curios to know if I pass through the incoming fax to an analog fax machine 
on another fxs line, the machine wouldn't receive the fax too?
Anyways, let me take the most benefit as im sure you'd read this post, i 
have problem with the size of received page which is shrinked, can u give me 
a hint about this problem too :)

Thanks.
