Emergency Number
Public telephone networks in countries around the world have a single emergency telephone
number (emergency services number), that allows a caller to contact local emergency services
for assistance when necessary. The emergency telephone number may differ from country to
country. It is typically a three-digit number so that it can be easily remembered and dialed
quickly. Some countries have a different emergency number for each of the different emergency
services.
You can specify the emergency telephone numbers on the IP phone for contacting the
emergency services in an emergency situation. You can dial these numbers when the phone is
locked. For more information on phone lock, refer to
