 Posted: Fri Jul 04, 2008 6:57 am Post subject: [asterisk-users] Removing voicemail messages |
 |
|
Hello,
I want to create an script which remove all the old voicemail messages.
I make a simple Bash script to delete all the new messages for the
extension 100. Something like,
rm /var/spool/asterisk/voicemail/defaul/100/INBOX
Should I update any index file or something after reemove them?
Thanks in advance

In my solution, I archive messages that haven't been touched in <x> number
days and send the compilation of messages being archived to the
voicemailbox's owner. You could modify to delete them and leave it at that.
Since I'm leaving newer messages in the directory, and Asterisk doesn't like
nonsequential filenames - I renumber all the remaining files.
I also had an issue with abandoned voicemail - where the caller would hangup
at the exact right moment leaving a zero length message. The .txt file
would be created but none of the audio formats. It was a rare occurrence -
but the user was unable to fix it from the phone interface meaning I had to
manually correct it every time, so I automated it with a script and a
cronjob.
My crack at these is below, these are a work in progress - use at your own
risk, suggested improvements are welcome.

#!/bin/bash
# Script to automatically archive old voicemail messages
# Based on modified date of files, when messages are listened to the date is
updated.
# Not an issue in this implementation as users mostly listen to e-mail
attachment and don't
# touch the phone.
# Archived messages are also e-mailed to the voicemailbox owner.
# Possible future iteration: Read the date of the messages directly from the
.txt file
# Future Improvement: Read options from config file to allow defaults and
mailbox
# specific modifications.
# Possible future improvement: Use AGI or other interface to allow users to
modify archive
# options via the telephone. If this proves too difficult, perhaps an e-mail
# or web interface would work.
