When I press the Apple button I get this error and the data is not being sent to the server.
I have purchased FAX PRO Commercial Module
exit: 255
Unable to continue. Critical error when splicing into outrt-4.
I was asked to splice into an empty section with a priority greater than 1.
This is always a bug in a module. I was asked to add null in /var/www/html/admin/libraries/extensions.class.php on line 234
#0 /var/www/html/admin/modules/faxpro/functions.inc/functions.inc.php(119): extensions->splice('outrt-4', '_1NXXNXXXXXX', 3, Object(ext_set))
#1 /var/www/html/admin/libraries/BMO/DialplanHooks.class.php(95): faxpro_get_config('asterisk')
#2 /var/lib/asterisk/bin/retrieve_conf(864): FreePBX\DialplanHooks->processHooks('asterisk', Array)
#3 {main}
PLEASE HELP
