# Softkey Settings
#
# Softkeys can be set either server wide or unique to each phone.
# Setting softkeys as line/call appearances should be done in the
# "<mac>.cfg" file, since these are unique to each phone.
# Notes:
#
# There are a maximum of 18 softkeys that can be configured on the
# 57i or 57iCT phone. These can be set up through either of the 2
# configuration files, depending on whether this is to be server wide
# ("aastra.cfg") or phone specific ("<mac>.cfg"). Each softkey needs
# to be numbered from 1 - 18, for example "softkey12 type:
# speeddial". Softkeys can be set up as speeddials or as additional
# call/line appearances and have a type, label and value associated
