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 Phone Lock on page 26.
