Holding a call
During a call it is possible to hold a caller so that he can not hear what is discussed
in the room. The telephone is switched to mute and the caller hears "Please hold
the line" followed by a hold tune. There is also the option of assigning one of the 14
individual OGMS to the holding loop (refer to Page 93 Settings/message on hold)
Press the selection button next to
t
he holding loop symbol for 2
seconds.
The display flashes "on hold". The
holding loop can be screened quietly via
t
he loudspeaker.
To retrieve the call press the
selection button next to the holding
loop symbol again.
The initial state is again displayed. You
can continue the call.

When making calls without a separate power supply it is not possible to
combine holding with hands-free operation.
Automatic redialling /Automatic call back when engaged
(CCBS)
If the person you are trying to call is constantly engaged your tiptel 570 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
system must support this function (refer also to your network operator and PABX
manufacturer user instructions). To activate "Call back on busy" you usually dial a
certain combination of digits (e.g. Hook flash *37#). The combination of digits must
be pre-entered as described in "Settings/Call back code" (Page 94).
