> The documentation for Voicemail notes that the externnotify script will be called whenever a voicemail message is left.  Provided that pollmailboxes is set to 'yes' and pollfreq is non-zero.  I have been unable to get the script to run when I've listened to the voicemail message via an email client.
> With debug sent to the messages log and turning on debug, I note:
> [asterisk at crpsvvoip001 asterisk]$ tail -f /var/log/asterisk/messages -n500 | grep mwi.pl
> [Jul 28 17:45:41] DEBUG[17349] app_voicemail.c: Executing /opt/asterisk/bin/mwi.pl (null) 134 at VREC 0 3 0 &
> [Jul 28 17:46:02] DEBUG[17358] app_voicemail.c: Executing /opt/asterisk/bin/mwi.pl VREC 134 1 3 0 &
> [Jul 28 17:46:11] DEBUG[17354] app_voicemail.c: Executing /opt/asterisk/bin/mwi.pl (null) 134 at VREC 1 3 0 &
> [Jul 28 17:47:11] DEBUG[17354] app_voicemail.c: Executing /opt/asterisk/bin/mwi.pl (null) 134 at VREC 0 4 0 &

> The only time the parameters will called with the correct order was when the message was left.  The times where is was called from the polling routine is incorrect and causes the script to be ignored.
> To perhaps make clearer what I'm trying to convey, the problem is like this:
> * A voicemail is left in a mailbox, in this case 134.
> * Asterisk executes properly the mwi script:
>      [Jul 28 17:46:02] DEBUG[17358] app_voicemail.c: Executing /opt/asterisk/bin/mwi.pl VREC 134 1 3 0 &
> * The voicemail is listened to (doesn't matter how)
> * Asterisk then executes the mwi script:
>       app_voicemail.c: Executing /opt/asterisk/bin/mwi.pl (null) 134 at VREC 0 3 0 &
> * Because of the (null) the script will not be executed by the shell.
