Compiled && installed w/o issue

This USED to work w/1.2 && older versions of rxfax:

co2
exten => s,1,NoOp(Inbound Call)
exten => s,2,NoOp(CALLERID=${CALLERID})
exten => s,3,Set(_menu=menu-000)
exten => s,4,Goto(fax,90)

; Queue and print
exten => fax,90,Set(FAXFILE=/var/spool/asterisk-fax/${UNIQUEID}.tif)
exten => fax,91,rxfax(${FAXFILE})
exten => fax,92,NoOp(REMOTESTATIONID ${REMOTESTATIONID})
exten => fax,93,NoOp(FAXPAGES ${FAXPAGES})
exten => fax,94,NoOp(FAXBITRATE ${FAXBITRATE})
exten => fax,95,NoOp(FAXRESOLUTION ${FAXRESOLUTION})
exten => fax,96,System(/usr/local/bin/printfax -p ${FAXPAGES} -r ${FAXRESOLUTION} ${FAXFILE})
exten => fax,97,NoOP(Fax Complete)
exten => fax,98,NoOP
exten => fax,99,Hangup


Now When the fax is done I don't get the printfax to run . . . (from the log):

I'm at a loss, I can think of a few work-arounds, but this must have something to do with a change in asterisk on a hangup. Processing stops now? Perhaps an explicit off-hook is needed. Any insight useful.

There is a newer package with installation instructions. I've never had any success with the instructions on this page with the latest versions of asterisk (>=1.4). If you don't have any luck with this stuff try AGX's Asterisk Extra AddOns instead and ignore the instructions above.

i have followed Ray step-by-step, installation is okay. i can see rxfax/txfax in show applications.

but the problem is really strange, i can receive fax successfully but rxfax keeps the channel up forever untill i softhangup the channel. here is the output

any idea why rxfax keeps running.

Where do I put the FAX DESTINATION NUMBER ?

ext-test-custom
exten => 667,1,Goto(ext-fax,out_fax,1)

ext-fax
exten => s,1,Answer
exten => s,2,Goto(in_fax,1)

exten => in_fax,2,GotoIf($"${FAX_RX}" = "system"?3:analog_fax,1)

exten => in_fax,5,Hangup

exten => analog_fax,2,Set(DIAL=${DB(DEVICE/${FAX_RX}/dial)});

exten => out_fax,5,SetVar(LOCALSTATIONID=company)
exten => out_fax,6,txfax(${TXFAX_NAME}|caller)
exten => out_fax,7,Hangup
exten => h,1,Hangup()

And another experience:
Asterisk 1.4.4, spandsp 0.0.3, Debian 4.0 etch, libtiff, autconf (2.61-4) and automake from the standard Debian 4.0 archive.

Don't remember how exactly i compiled spandsp, but for Asterisk 1.4.2 and Asterisk 1.4.4, i didn't do autconf in
autoconf
./bootstrap.sh
./configure
make menuselect
just boststrap.sh in a FRESH unzipped asterisk-1.4.x dir was enough.
I use the app-r/tx.c files from January 2007, the latest are from June 2007, haven't tested them.
If you have problems, also check, if app_t/rxfax.so are linked against libspandsp and libtiff (with ldd apps/app_rxfax.so)

Edit /BTW: Haven't had the problem that Leonardo reported.

First of all, thanks Ray Collett for the tips.

I've compiled it exactly as Ray's comment below, but with a bit difference when re-creating the Makefile with bootstrap.sh

I'm using:
Asterisk 1.4.4
SpanDSP 0.0.3: http://www.soft-switch.org/downloads/spandsp/spandsp-0.0.3.tgz

Hint: The autoconf 2.6 or above and automake are essentially.

Do the same things that Ray said below, then after run ./bootstrap.sh, it re-creates the configure file, but it merge the SPEEX and SPANDSP session incorrectly. So, open the configure, find the SPANDSP session (below the RADIUS), then remove everything from SPANDSP and SPEEX (there are lot of things repeated). The clean code is this:

SPANDSP_DESCRIP="spandsp Library"
SPANDSP_OPTION="spandsp"

if test "${with_spandsp+set}" = set; then
 withval=$with_spandsp;
case ${withval} in
    n|no)
    USE_SPANDSP=no
    ;;
    y|ye|yes)
    SPANDSP_MANDATORY="yes"
    ;;
    *)
    SPANDSP_DIR="${withval}"
    SPANDSP_MANDATORY="yes"
    ;;
esac

fi

PBX_SPANDSP=0





SPEEX_DESCRIP="Speex"
SPEEX_OPTION="speex"

if test "${with_speex+set}" = set; then
 withval=$with_speex;
case ${withval} in
    n|no)
    USE_SPEEX=no
    ;;
    y|ye|yes)
    SPEEX_MANDATORY="yes"
    ;;
    *)
    SPEEX_DIR="${withval}"
    SPEEX_MANDATORY="yes"
    ;;
esac

fi

PBX_SPEEX=0


Now just continue with ./configure and the next steps.

Ray, did you tested sending/receiving a fax?
I followed your instructions; compiling was ok, but when invoking rxfax asterisk instantly dies...

I spent about 5 hours today trying to get this all to work. Here is the process that I used to get it to install:<BR>
(using an older Fedora 3 i686 system)<BR><BR>

wget http://ftp.digium.com/pub/asterisk/releases/asterisk-1.4.2.tar.gz<BR>
wget http://www.soft-switch.org/downloads/snapshots/spandsp/spandsp-20070413.tar.gz<BR>
wget http://www.soft-switch.org/downloads/snapshots/spandsp/test-apps-asterisk-1.4/app_rxfax.c<BR>
wget http://www.soft-switch.org/downloads/snapshots/spandsp/test-apps-asterisk-1.4/app_txfax.c<BR>
wget http://www.soft-switch.org/downloads/snapshots/spandsp/test-apps-asterisk-1.4/asterisk.patch<BR><BR>

tar -zxvf spandsp-20070413.tar.gz<BR>
cd spandsp-0.0.4<BR>
make uninstall<BR>
make clean<BR>
autoconf<BR>
./configure<BR>
make<BR>
make install<BR><BR>

tar -zxvf asterisk-1.4.2.tar.gz<BR>
cd asterisk-1.4.2<BR>
cp ../asterisk.patch .<BR>
cp ../app_rxfax.c apps/<BR>
cp ../app_txfax.c apps/<BR><BR>

(at this point, you SHOULD be able to do "patch -bp0 < asterisk.patch", but the patch is partially broken. Look at the asterisk.patch and you'll see several different sections where the patch looks for one block of text in a certain file, then inserts the lines that starts with the "+". You need to manually add the lines with the "+" character into the spots that the patch file point to. Remember to remove the "+" from the beginning of the line.)<BR><BR>

cp /usr/local/include/spandsp/plc.h include/asterisk/plc.h<BR><BR>

(I had to copy the plc.h that was installed from the spandsp into the asterisk folder to get around some error messages)<BR><BR>

make clean<BR>
autoconf<BR>
./bootstrap.sh<BR>
./configure<BR>
make menuselect<BR><BR>

(at this point, check to see if the app_txfax and app_rxfax are selected. It should not be marked as unavailable, ie., no XXX's)<BR><BR>

make<BR>
make install<BR><BR>

If it compiles without error, If it does not coredump when you run asterisk, you should be able to see usage information from the console by running these commands:<BR>
core show application RxFax<BR>
core show application TxFax<BR><BR>

I had to manually upgrade my autoconf, because there are no RPM's for autoconf 2.6 or newer.<BR><BR>

Ray

Here there is another patch, but for different purposes. This patch allows to consult the successfully state of the transmitted fax, the status is show in the variable "RESULTADO". To apply the patch:

1. patch app_txfax.c < app_txfax.patch

The complete post is here.</p>

OK. To answer my own question, I found an updated app_rxfax.c, app_txfax.c and a patch file for asterisk 1.4 in http://www.soft-switch.org/downloads/snapshots/spandsp/test-apps-asterisk-1.4. The patch must be for a beta of 1.4 as it didn't quite work (patch -p0) but it was easy enough to figure out how to fix the issues. Then I did a ./configure; make; make install and the modules were copied to /usr/lib/asterisk/modules. Note that the patch does not attempt to patch menuselect so there is no fax entry when you do a make menuselect.
