[Freeswitch-users] [Freeswitch-dev] How to check the "fax_result_code" in the script? such as php script?

[Nathan Neulinger]

Can't help you on the PHP side, but I do this with sending a fax with perl based web page. If you're wanting to do it 
inline, I think you'd have to listen for events as you've described...

...
     push( @args, "fax_notify_address='" . $ENV{REMOTE_USER} . "\@mst.edu'" );
     push( @args, "api_hangup_hook='perl /local/freeswitch/bin/notify-fax-status-hook.pl'" );
...


and then the attached script.

Key parts:


our $env;
our $session;
my $addr     = $session->getVariable("fax_notify_address");
my $to       = $session->getVariable("destination_number");
...
     my $fax_status = $session->getVariable("fax_success");
     my $status_msg = "Sent OK";
     if ( $fax_status != 1 ) {
         $status_msg = "Failed";
     }
     my $result = $session->getVariable("fax_result_text");
