# This was created because we had a need. If you're considering
# using this, you have that same need. While I'm not particularly
# good at scripting, as you can tell by how this is written, this
# SHOULD be pretty safe to run without negatively affecting your
# HQ/DVS, as we only read from them.
#
# This script DOES NOT write to them at all.
#
# Any modifications only occur to files that have been copied to
# your local computer, NOT on HQ/DVS, so I think this is safe.
#
# Also, I wrote this for running from my Mac. Needless to say,
# customize everything to fit your environment.
#
# That being said, read through this fully, and by running this,
# you assume all risks and responsibilities associated with it.

# This checks to make sure that the extension you entered, has a
# mailbox associated with it on HQ/DVS. If not, it will exit.
#
# If there is a mailbox, then it will create a directory with the
# current date and time, followed by the extension on the Desktop.
# Then we throw that path into a variable, so a new directory is
# not created with each passing second the script is running.
#
# This is just for organization. I like having the voicemails
# dumped into a folder on my desktop. Change as you like.

# So the for loop removes the binary from the Mailbox.dat file,
# then we awk for anything that is exactly 9 characters, which for
# our environment is the Message ID, which we want.
#
# Each voicemail has two components:
# - the WAV file: the actual audio.
# - the MSG file: this is what you receive in Communicator,
#   informing you that you have a message. The MSG file contains
#   information about the voicemail. We are want the Caller ID.
# You will only have either a WAV AND MSG, or only a MSG.
#
# So, we find all the Message IDs, then check if there is a WAV
# with that ID. If so, tell us there is, then copy the file
# (with -p to preserve file attributes, such as Date Modified) to
# the directory created above. After that, inform us that renaming
# will take place. We are renaming the file from the Message ID to
# include the following information:
# - Date Modified: when the message was received (YYYY-MMDD_HHMMSS)
# - Caller ID: which we are awking from the MSG file.
