Making an emergency call
About this task
You do not have to be logged in to make an emergency call. If emergency calling was set up
by your system administrator, the Phone screen has an Emergency softkey to immediately
connect you with a preset emergency services number.
Important:
During telephone failover (switching between telephone system servers during a system
failure) the Emergency softkey may not be available until your telephone is connected with
an alternate server, usually within several seconds.
Procedure
1. Press the Emerg. softkey. If you do not see an Emerg. softkey, pick up the handset
or press the Phone button, then press the Emerg. softkey.
2. If the telephone prompts "Do you want to make an emergency call?" press the Yes
softkey.
