[Asterisk-bsd] app_rxfax

[Alex Ayala]

Ok I got Rxfax and Txfax applications to load fine when I start asterisk.
But now I'm having problems getting rxfax to work.  It worked twice and
after that I get nothing when sending a fax to asterisk.  In the logs I
notice this:

Other times I get training error.  From what I've read around this could be
because of jitter or bad connection?? But why did it work the first two
times and then never again. And no tiff file is created.

This is my extention.conf
exten => s,1,wait(2)
exten => s,2,Answer()
exten => s,3,NVFaxDetect()
exten => s,4,Background(english2)
exten => fax,1,goto(fax,s,1)

[fax]
exten => s,1,SetVar(FAXFILE=/tmp/${UNIQUEID}.tif)
exten => s,2,SetVar(EMAILADDR=blah)
exten => s,3,rxfax(${FAXFILE}|debug)
;exten => h,1,system(/usr/local/sbin/mailfax ${FAXFILE} ${EMAILADDR}
${CALLERIDN
UM})


I'm using FBSD 5.3, Asterisk 1.09 latest from ports and spandsp 0.0.2-pre18
from ports.  If anyone knows what could be causing the problem please let me
know.

Thanks,

Alex
