# ViciDial Init Script for systemd (openSUSE 15.3+ and 16.0)

# Author: James Pearson, feedback at www.vicidial.org in vicibox forum

### BEGIN INIT INFO
# Provides:          vicidial
# Required-Start:    $syslog $local_fs $network
# Should-Start:      $time mysql
# Required-Stop:     $syslog $local_fs $network
# Should-Stop:       mysql
# Default-Start:     3 4 5
# Default-Stop:      0 1 2 6
# Short-Description: ViciDial Telephony Server
# Description:
#       Starts ViciDial services and drivers that are needed to operate
#       a telephony server including DAHDI and Asterisk. Wanpipe and
#       VoiceSync are loaded if hardware is detected otherwise just
#       dahdi_dummy is loaded for a timing source.
