Summary:                    system() dialplan function does not work
Description: 
You can put any script passed as an argument to the system() command in a
dialplan and it will not execute.  In my example, I created the following
script:

#!/bin/bash
ls -l /tmp > /usr/src/temp.txt

in file /usr/src/temp.sh.  temp.sh is 755 so any user can execute it.  In
the dialplan I put a simple call to system using this dialplan

exten => 101,1,Set(__FROM_DID=${EXTEN})
exten => 101,n,system(/usr/src/temp.sh)

The asterisk log shows

[Feb 25 15:12:11] VERBOSE[23375] pbx.c:     -- Executing
[101 at from-trunk:1] ^[[1;36mSet^[[0m("^[[1;35mSIP/DefaultOut-00000006^[[0m",
"^[[1;35m__FROM_DID=[Feb 25 15:12:11] VERBOSE[23375] pbx.c:     --
Executing [101 at from-trunk:2]
^[[1;36mSystem^[[0m("^[[1;35mSIP/DefaultOut-00000006^[[0m",
"^[[1;35m/usr/src/temp.sh^[[0m") in new stack

The script does not execute as there is no output file /usr/src/temp.txt.

Executing the command from the asterisk command line as
"!/usr/src/temp.sh" DOES work without issue.

Yes, it was a permissions issue.  I went out of my way to check that before
submitting but obviously didn't do the job.  How embarrassing.

The reason I opened the ticket is fax-process.pl isn't executing as part
of the FreePBX dialplan.  I can run the command find from the command line
as the asterisk user but the command does not seem to execute in the
dialplan. 

I created a simple dialplan like I did for this test and the command ran
fine so it must be something in the FreePBX dialplan.  

Sorry for jumping the gun on this ticket.  It can be closed.
