Defining an Emergency Dial Plan
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 required. 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 digits to dial on the IP phone for contacting emergency
services. Once you specify the emergency number(s) on the phone, you can dial
those numbers directly on the dial pad when required and the phone automatically
dials to those emergency services.
The following table describes the default emergency numbers on the IP phones.
You can set the emergency dial plan via the configuration files or the Aastra Web
UI.
Note:
Contact your local phone service provider for available emergency
numbers in your area.
