Ringing signals
Three different ringing 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 a differing signal for
one or more situations. If you get a signal that is not described or
you cannot identify, ask your system administrator.
Internal ringing signal
External ringing signal
Recall signal
(automatic callback
reminder)
Note: If you use a melody for the external or recall
ringing signal, the melody will be repeated in the same
way as for internal calls.
