Preface
Making Emergency Calls: Important Information!
NOTE: Remote IP phone users should never make emergency calls using the
AastraLink Pro 160, because the location information will be incorrect. 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 Pro 160 Lifeline port
(for example, FXO Line 1), rather than the address where the remote IP phone is
installed.
Warning: 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.
