Ring signals
Three different ring signals inform you about the type of the
incoming call. The signals shown in this section are the most used
signals worldwide. Many markets use signals that are adapted for
the local standards. If you get a signal that is not described or you
cannot identify, ask your system administrator.
The Monitoring keys can be programmed with other ring options,
see section “Change ring signal for a Monitoring key” on page 77.
