>From couple of weeks i am working on asterisk fax but was not
successful.
I am able to receive only half fax documents and its ending with blurred
lines.
I have tried with almost all the versions of spandsp 0.0.2pre4,pre10
etc but of      no use.

I have digium card to which i have plugged in 2 pstn lines and i have
removed echocancellation too(zapata.conf) and also enabled g7111
alaw&Ulaw codecs. When ever i receive a fax it will come upto some
extension(half) and ends.I even checked the pstn lines but its working
fine.
Please look into it and help me to get rid off.

BELOW ARE THE LOGS I HAVE GOT :

= Spawn extension (zapincoming, fax, 0) exited non-zero on 'Zap/2-1'
