Hi Anthony,<br><br>I started up the FS process, sent myself a fax which was successfully received and ran:<br><br>gdb --batch --command=fs_debug.cmd --pid=`cat /opt/freeswitch/log/freeswitch.pid` /opt/freeswitch/bin/freeswitch >> fs_debug.txt<br>
<br>Where fs_debug.cmd is:<br><br>bt<br>bt full<br>thread apply all bt<br>thread apply all bt full<br><br>I hope this is the right process to get you something useful for debugging purposes. I've attached the fs_debug.txt file.<br>

Good old fashioned "bump" mailing-list style :-) I'm mainly concerned with 2) .. any ideas as to why the channel never gets hanged up? I had a look at the mod_fax.c code and it doesn't hang up the channel once a fax transmission ends so it should return to the dialplan .. right? The next application to execute should be "hangup" but it never does.<br>

Hi,<br><br>Nice work on mod_fax! I just tried sending myself a couple of faxes and they were received successfully. I even tried using tone_detect which correctly detected the fax machine and fired off rxfax.<br><br>I wanted to report back on a couple of issues:<br>
<br>1) Even though the spool dir is set to /tmp/, I called up rxfax with data="rxfax.tiff" and it saved it in /. Shouldn't it save it in the spool dir?<br><br>2) After receiving the fax, the channel is never hanged up. The tone_detect app even detects the busy tone (which calls the hangup application when it detects it) but it just sits there for a long time until I manually uuid_kill it. Log says:<br>
