Receivefax stopped working

Distro Discussion & Help
1

Using the latest Freepbx w/sipstation my faxes stopped working. Only thing I can think of that I did was “asterisk-version-switch” to asterisk 13. I notice the log says “No application ‘ReceiveFAX’ for extension (ext-fax, s, 4)”. core show applications does not show receivefax. Log…

Switch back to 11? See if it works

3

Downgraded to 11 and receivefax shows with “core show applications” and fax works. Any idea on why receivefax isn’t in asterisk 13?

@GameGamer43 ^^^^^^^^

The ReceiveFax and SendFax applications are provided by the generic FAX resource module (res_fax.so). The most likely cause of the issue you’re experiencing is because res_fax.so is unable to parse /etc/asterisk/res_fax.conf. This can be caused by an incorrect configuration such as min/max_rate not being set. You will be able to see this is you do the following in the asterisk cli:

module load res_fax.so

The output will be something like:

Unable to load module res_fax.so
Command 'module load res_fax.so' failed.

To help us determine why this is happen, we need the following output (preferably in a bug ticket for tracking purposes):

  • cat /etc/asterisk/res_fax.conf
  • echo 'SELECT * from fax_details' | amportal a m

Do you want me to switch back to asterisk 13 before I run these commands?

7

The last two you can run them without switching Asterisk back to 13. In order to see the reason for the failure, you will need to switch back to Asterisk 13 to reproduce the issue.

8

Here are the last two commands. I’ll switch back to 13 after we close and post the results.
(I obscured the email and phone numbers)

[root@freepbx ~]# cat /etc/asterisk/res_fax.conf
[general]
#include res_fax_custom.conf
minrate=2400
maxrate=14400
[root@freepbx ~]# echo 'SELECT * from fax_details' | amportal a m

I’ll put this in a ticket but I have to get logged in and buy credits.

12

So this looks like a change that was made in asterisk but the change never made it to 13?. 2400 isn’t supported with v27 and that prevents the module load so maybe freepbx should remove that value from the list?

13

Asterisk needs to fix this in 13 as it operates in every other version fine and we can not set baud rates on a per V style. Its global

14

yeah but if 2400 isn’t a valid option and we don’t have access to the “modem” (v setting) why have it there?

15

If you feel it’s a bug in FreePBX you can of course report it for free on http://issues.freepbx.org but of course as Tony said it’s primarily an Asterisk bug and should be brought up there as well.

16

I guess I’ll just let it go. I know the work-around. Thanks for all your help!!
