Automatic redialling /Automatic call back when engaged
(CCBS)
If the person you are trying to call is constantly engaged your tiptel 540 SD can take
over by repeatedly trying to call the other person. For automatic re-dialling if the
caller is engaged there is a pause and the device repeats the dialling up to 10
times. With the "Call back if engaged" function a call is signalled to you as soon as
the person you are trying to reach is free. Your telephone network or extension sys-
tem must support this function (refer also to your network operator and PABX man-
ufacturer user instructions). To activate "Call back on busy" you usually dial a cer-
tain combination of digits (e.g. Hook flash *37#). The combination of digits must be
pre-entered as described in "Settings/Call back code" (Page 82).
