the echo.
Emergency Call
To make an emergency call, dial 911 or Access Code + 911. This depends on
off-hook preference set up for your telephone.
Note Check with your System Administrator for the Access Code because this code
may be different from the one used to get an outside line.
Emergency Monitoring Station
Your system may have one IP telephone assigned as an emergency monitoring station.
If your telephone has this assignment, your line LED will flash green when someone
makes a
911 call. When you answer the call, you can listen in and participate in the
conversation. See your System Administrator for more information on this feature.
