5.35 Emergency Call Numbers
Up to five different phone numbers may be reserved for emergency calls. These numbers
can always be called even when the phone or key locks are active.
NOTE: if emergency numbers of varying length are used, care
must be taken to ensure that
longer numbers do not begin with the same digits and ordering used by a shorter number.
For example, if 124 and 1245 define two emergency numbers, the number 1245 cannot be
used because 124 is always evaluated and called before the longer number can be entered.
However, 5421 and 1256 would be allowed.
Emergency numbers are configured using the PDM/Device Mana
ger
and setting the value of
the parameter:
