    Trevor - 2017-04-14

    So I have tried with a fresh image from both Jan of this year and the Sept release from 2016. I go in, do the updates, set the time zone, then install-fax. I setup extension 150. If I try to call the 150 extension from another extension or if I point a inbound route to the extension, each time I get a fast busy when it hits. I cannot seem to figure out how to get it to work. Is this a known issue? Is there another route I should try to resolve? What logs or data would be helpful. Hoping someone might be able to help, thanks in advance! (Running this on a Pi3, 16GB card, tried another Pi3 I have as well, same result).

    This issue can be resolved with the following steps:
    1. Edit extension 150 in FreePBX and change host from localhost to 127.0.0.1 in the advanced tab. Click the Apply Config button.
    2. Edit /etc/iaxmodem/ttyI150 and change

    server localhost
    

    to

    server 127.0.0.1
    

    Reboot. The problem has been described before:
    https://sourceforge.net/p/raspbx/discussion/general/thread/37e14c65/

    Obviously an issue appeared with connecting to localhost through IPv6 at some point...

    I've fixed the add-fax-extension script accordingly. You can get it with the usual updates. But before calling the updated add-fax-extension script delete this file:

    rm /var/www/html/createext.php
    

    Let me know if it finally works.

    Hello to all
    I am having similar problems on two systems using the 03-12-2017 raspbx image. I have upgraded it to fix 27.

    Under asterisk iax settings I have added

    calltokenoptional=0.0.0.0/0.0.0.0
    maxcallnumbers=16382
    requirecalltoken=no
    

    Running iax2 show peers displays the extension as ok with 1-3 ms
    After looking in the log file of iaxmodem under /var/log/iaxmodem/ttyIXXX I saw that the extension failed to register.

    After a full rebuild of one of the systems using the same image and steps the fax is working.

    Justo to update. In my case the problems was a codec issue. After adding alaw to the empty allow codecs and all to the deny codec field of the iax extension in freepbx all was well.

    Looking at the add-fax-extension script at line 343 the variables devinfodisallow and devinfoallow should be set to something. Also at line 335 callwaiting should be disabled for this extension.
