Hi all,<BR>
<BR>
I was having a similar issue, using TE110P from Digium all incoming faxes<BR>
were detected and correctly received.<BR>
<BR>
When trying to send outbound faxes, they all get broken... I do believe it<BR>
may be related with Echo Cancel enabled on my Zapata.conf, any ways i've set<BR>
also fax detect for inbound and outbound on zapata, but that stills diferent<BR>
from the receiving model as it relies on NVfaxdetect to detect.<BR>
<BR>
After many trials, i setup an architecture with another Server Running<BR>
Hylafax and IAXmodem registring on my * Box and i just get out of troubles.<BR>
<BR>
It's perfect sending and receiving faxes with notifications and everything<BR>
else, Hylafax + IAXmodem and Asterisk are working like a charm.<BR>
<BR>
I must say that we don't send too many faxes per day, but until now no<BR>
problems! And yes didn't change anything on Zapata config or something else<BR>
on Asterisk Box, i just added IAX account registred my Hylafax IAXmodem<BR>
there and Voilá :)<BR>
