Hello Moises,
thx. Well I saw a hint for noise reduction capabilities of A104d somewhere in the logs during debugging. And it's easy to suppose that fax data could be interpreted as noise. On the other hand I'm a bit confused because the Fax is transmitted in a digital way, so where should the noise comes from (except the quantization noise).
Noise could come from analog line "on the other side", for example this is 2 phones (one being facsimile machine) put in parallel to one pair of copper line. I run some big faxserver farm (like having 20+ channels up most of the 9-17 on one machine and having two machines in two different locations) and prefer to use some openvox cards without any EC (hardware or software). with A102d i had some problems that caused need to reboot server with a reset button every two-three weeks. btw: i use dedicated machine just for faxing, for you disable 'on demant' might work better. what software you use for fax? (iaxmodem/ t38modem + hylafax or you do faxes in FS ?) and what speed you manage to get (14 400 bps or some more)?
