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.
Note: Contact your local phone service provider for available emergency numbers in
your area.
The following table describes the default emergency numbers on the IP
phones.
