Note
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 different emergency
numbers for different emergency services.
You can specify the emergency telephone number on the IP phone for contacting the
emergency services in an emergency situation.
Note
To specify emergency numbers via web user interface:
