Asterisk Externnotify in voicemail.conf not running the assigned script

Posted on 2009-07-14

Last Modified: 2013-11-12
Using asterisk 1.4.25.    In the voicemail.conf file we assign a script to the externnotify parameter so that this script would execute whenever a voicemail is left.    The script simple will turn on the message waiting indicator on cisco phones (for testing purposes we have it just echoing text into a file).  

Manually, the script runs.  And turns on the MWI on the phones.  

From the conf file, it does not.  

Asterisk is running as root and we test the file as root as well.  

Suggestions on why the script is not executing are welcome.

If you need additional info, please post on what you would liek to see.

Also, did you do a "reload" after making the changes to voicemail.conf ?

; Voicemail Configuration
; NOTE: Asterisk has to edit this file to change a user's password.  This does
; not currently work with the "#include <file>" directive for Asterisk
; configuration files, nor when using realtime static configuration.
; Do not use them with this configuration file.
; Formats for writing Voicemail.  Note that when using IMAP storage for
; voicemail, only the first format specified will be used.
; If you change the list of formats that you record voicemail in
; when you have mailboxes that contain messages, you _MUST_ absolutely
; manually go through those mailboxes and convert/delete/add the
; the message files so that they appear to have been stored using
; your new format list. If you don't do this, very unpleasant
; things may happen to your users while they are retrieving and
; manipulating their voicemail.
; In other words: don't change the format list on a production system
; unless you are _VERY_  sure that you know what you are doing and are
; prepared for the consequences.
; Who the e-mail notification should appear to come from

; The default is no minimum.
; Maximum length of greetings in seconds
; How many milliseconds to skip forward/back when rew/ff in message playback

I noticed there is no file extension...

Did you try ....

Yep.  Our first attempts used 'vm.sh' as the script.    No difference.  

Everything with the script works when executed outside of asterisk.   Its just not getting called from asterisk when the new voicemail arrives....

Is there any detailed logging available in asterisk aside from the default /var/log stuff.    We need to see if the file is even attempting to run.

I'm testing this on my box, and i'm having the exact same issue....

It simply doesn't get executed.
I'm also running the same version you are....on CentOS.

Ok,... I GOT IT WORKING.....

I have  absolutely no idea why this makes any difference.... but I put my script in /root/

Echo "TEST" > /root/testfile

....testfile was created after leaving a message.

Well, it is still odd.    Using your suggestion we found that having the script go to /tmp first then mv the file to the outgoing folder seems to work for us.  

I can't explain why it likes /tmp and not the other dirs we tried since they all had the same security.    

But whatever, its working for now.  

Thanks for the tip.

I talked to someone else on a digium forum, who also used the tmp dir, and it worked for them too.

I think the wiki needs to be updated.

If I had to guess I would say it's due to OS security, ..permissions for applications executing scripts from system directories ?..who knows....
