# Sangoma Tech Support Script

# April 09 2011 Moises Silva <moy@sangoma.com> -- initial version

# This script is aimed to collect all kind of information that can be useful for
# a tech support engineer to get an idea of what is running in the customer
# computer and give an initial assesment of the problems 

# NOTE: Try to avoid printing errors, either log them or discard them by sending them to /dev/null, some commands
# are meant to fail in some Linux distributions

# TODO
# - Make major directories (/usr/local/freeswitch for example) configurable thru cmd line option --fsdir=/opt/freeswitch
# - Add support for Ubuntu, Debian and SuSE (ie: retrieve list of packages installed and check specific distro version)
