[Asterisk-Users] txfax application problem

[Technical Support]

The docs for spandsp say that 0.0.3 is purely experimental/developmental.
Don't expect it to work!  (I would be surprised if you got everything to
compile without warnings).  Stick with the latest in the 0.0.2 family.

After that, you would have to follow a logical diagnostic process and post
relevant data.  Based on your previous posts, I don't even know if asterisk
is complaining about the call file during fax out (no debug logs) etc.

Post all the relevant details and you'll find the list very helpful!  If you
have not paid attention to compile warnings, mixed library versions, etc.,
you may have to pay someone to go onto your system to untangle the mess (or
post your problems and analysis one step at a time).

Thanks for the tip but if I am using Asterisk 1.2.X I can ONLY use
spandsp-0.0.2pre21 and up.
The earlier ones don't compile against 1.2.X

I have done reading spandsp docs and nowhere does it say what works and what
does not.
Which version of spandsp/asterisk works for you?

Downgrade your spandsp.  Do some reading on spandsp first!

Nobody seems to use txfax or does nobody have any problems with it?
I have sent mails to most lists and get no reply.
I cannot get a fax to go through with txfax.
I use a call file as a test and all I get on the receiving fax is a bunch of
vertical lines.

my call file is:

Channel:Srx/gout/4658158
MaxRetries: 0
WaitTime: 20
Application:txfax
Data:/etc/asterisk/testfax.tif|caller|debug

FYI tiffinfo on file is:

TIFF Directory at offset 0x733e
  Image Width: 1728 Image Length: 1161
  Resolution: 77, 38.5 pixels/cm
  Bits/Sample: 1
  Compression Scheme: CCITT Group 3
  Photometric Interpretation: min-is-white
  FillOrder: lsb-to-msb
  Date & Time: "2006/01/11 18:06:14"
  Host Computer: "asterisk.equation.co.za"
  Orientation: row 0 top, col 0 lhs
  Samples/Pixel: 1
  Rows/Strip: (infinite)
  Planar Configuration: single image plane
  Page Number: 0-1
  Software: spandsp
  Group 3 Options: 2-d encoding+EOL padding (5 = 0x5)
  Fax Data: clean (0 = 0x0)
  Fax Receive Time: 29 secs

what is going on here?
I have used latest spandsp-0.0.3pre23 with it's app_txfax.c and tiff-3.7.1
from source I have also used just about every other spandsp and libtiff
combo but no joy with sending the faxes.

PLEASE HELP!!
