[Asterisk-Users] Numbered Voicemails even with delete option!

[David Waugh]

Hello,

Thought people might be interested in this.

I want my voicemails emailed to a person and not stored on my asterisk
server. However, I want them to have a sequential number. I found that
if I set the option delete=1 in my voicemail.conf file for the mailbox,
then the numbering would keep being restarted.

I wrote this shell script to fool Asterisk into numbering my voicemails
sequentially even though I delete them. The files asterisk required are
replced with 2 byte files with the same name. It's these files that
asterisk uses for numbering the voicemails.

In voicemail.conf change your voicemail user so that emails are no
longer deleted.

1234 => 4242,Eicon Support,voicemail

Here is the shell script. Watch out for line wraps!! This script should
be run as a cron job at whatever interval you like.

NOTE: This is my first shell script so I'm sure it can be improved!
