appears on the other party’s row on your graphic display. You can opt
to have voice connections that are no longer secure indicated by a brief alerting
tone and a window with the message "Unencrypted call" (see
Page 225).
Emergency mode
If a failover system has been set up for your OpenScape Voice, you can still
make calls and use the functions of the failover system, for example, despite
network faults.
If it happens that your telephone is no longer connected to OpenScape Voice, it
is registered automatically on the configured failover system. The message
"Emergency mode (B8)" then appears on the display.
Some functions may not be accessible while in emergency mode, for example:
