AastraLink Pro 160 IP Phone User Guide
Using the 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.
The following table describes the default emergency numbers on your IP phone.
Warning: Remote IP phone users (i.e., IP phones installed at a remote site or home office)
should never make emergency calls using the AastraLink Pro 160, because the location
information will be incorrect. On remote phones connected to the AastraLink Pro 160, the
following emergency related message displays: “E911 calls are not available from this phone.”
The phone user must press DONE to acknowledge the message.
E911 regulations in the United States require street address location information be transmitted to
the PSAP. This information is provided by the telco, using the location of the analogue line
connected to the AastraLink Lifeline port (FXO Line 1), rather than the address where the remote
IP phone is installed.
