AastraLink Pro 160 Emergency Call Support
Emergency Call Support Important Notes
Note: The AastraLink Pro 160 guarantees only one emergency call at a time. If multiple emergency calls are attempted, callers may receive a message stating that all circuits are busy. A call placed from a phone connected to FXS B receives the highest priority; it will not be terminated, even by another 911 call. If a 911 call is made, and the only available FXO line is already in use by a phone connected to FXS B, then the AastraLink will attempt to place the 911 call using SIP trunking.
Warning: On remote phones connected to the AastraLink Pro 160, the following emergency
related message displays: “E911 calls are not available from this phone.” Remote IP phone users should not 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 Public Safety Answering Point (PSAP). This information is provided by the telco, using the location of the analogue line connected to the AastraLink Pro 160 Lifeline port (FXO Line 1).
