The following table describes the labels in this screen.
34.5 The Emergency Call Screen
The ISG50 allows you to specify and give higher priority to emergency calls to emergency services.
You can configure a list of emergency phone numbers, for example police or fire department, on the
ISG50. The ISG50 recognizes when an emergency number is dialed and tries to send the call to the
configured destination number. If all the lines on the ISG50 are busy, the ISG50 frees up a line by
hanging up an existing conversation and then passing the emergency call to the destination
number.
An FXO or BRI outside line has higher priority than a SIP trunk for emergency call use.
