Automatic call-back on busy (CCBS)
Should the desired target subscriber's line be busy, the display shows a selection field for auto-
matic redialling and the automatic call-back function, i. e. the function completion of call to busy
subscriber. This special feature needs to be released by your telephone network provider. This
is not only valid for your installation, but also for the target subscriber's installation. Just replace
the handset if you do not wish to use this function. The corresponding menu line is only shown
in the display if the CCBS feature is available.
