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 emergency calls on the IP phone
even when the phone keyboard is locked. For more information on phone lock, refer to Phone
Lock on page 35.
Note
The default value of minimum and maximum length is 1 and 15 respectively.
Area code is configurable via web user interface only.
Block out number is configurable via web user interface only.
Contact your local phone service provider for available emergency numbers in your area.
The IP phone also supports the emergency dialplan, which allows users to make emergency calls
if the phone is locked or unregistered. For more information, contact your system administrator.
