2.7.2. Life line (PC#1, PC#2 only)
Life line feature allows specification of emergency number patterns to seize a PSTN
line with absolute priority. For example, someone dials an emergency call while all
PSTN lines are in use. In such case, if the called number matches any specified
pattern, the PSTN line with longest talk time so far will be disconnected right away to
allow the connection of the emergency call.
