AastraLink Pro 160 Emergency Call Support

Because IP phones and data networks require power to operate, they do not provide the fail-safe emergency calling capability of a traditional analogue phone. The AastraLink Pro 160 supports emergency calling in two ways:

•Lifeline Phone

•Emergency Call Priority

These features are described in detail in the next sections.

Lifeline Phone

The FXO Line 1 and FXS Phone B ports are labelled ⎯♥⎯ on the rear of the AastraLink unit. These ports provide capability for calling emergency services (also known as E911 in North America). In the event of power failure, the AastraLink Pro 160 hardware connects these two ports directly together, so that you can make an emergency call on FXO Line 1 using an analogue phone connected to the FXS Phone B port.

To ensure emergency call routing is available, we recommended that:

•You connect a traditional analogue phone to FXS B at all times, labelled as the E911 Lifeline emergency phone.

•When connecting telephone lines, connect the LifeLine FXO port first.

Emergency Call Priority

When the AastraLink Pro 160 is active, and an emergency call (by default, 911 or 9911 in North America) is made from an IP phone, it is preferentially routed to any available FXO line. If all FXO lines are in use, AastraLink Pro overrides any existing non-emergency call in progress on the Lifeline FXO and routes the emergency call in its place. Emergency Call Priority Override may take up to 15 seconds for the existing call to be cleared; an announcement plays during the override operation.

You can use the Web UI to provision emergency call numbers.
