# Trivial script to control an Siemens S675/S685IP VoIP DECT base
#
# Usage:
#
# s675.bsh PUT <handset port number, starting at 0> <filename>
# -> upload a .vcf phonebook file to the handset
#
# s675.bsh GET <handset port number, starting at 0> <filename>
# -> download handset phonebook as .vcf file
#
# s675.bsh CLEAR <handset port number>
# -> clear phonebook of given handset
#
# s675.bsh REBOOT
# -> reboot base by toggling the G729 Annex B (silence surpression) switch
#
# Written by Oliver Wagner <owagner@vapor.com>, Public Domain
#
# Notes:
# - no other session may be active when running the script, otherwise, the login will fail.
# - vcf files must have \r\n line endings and, for all current handsets, be UTF-8 encoded.
#
# Configuration: IP and PIN of the base station
#
S675IP=192.168.0.15
PIN=4711
