Wrong time, or wrong
date.
The handset hasn't received the
right time and date from the NTP
server.

administrator.
The handset calls an
emergency number
when trying to call
another handset, or
when calling an
international number.
NOTE: Cellular handset
version only.
The number sequence begins with
the same numbers as an
emergency number. Usually the
handset receives a list of locally
used emergency numbers from
the SIM card, but if no SIM card is
inserted a general list of possible
emergency numbers is used
instead.
If the handset is used without a
SIM card, insert a SIM card to
limit the number of possible
emergency numbers.
