Waiting Calls
When the “Call Waiting” feature is enabled and you are
conducting a call, you will be notified as soon as an exter-
nal call arrives on your line. This call will be signaled by an
acoustic signal in the handset. You can accept the connec-
tion with the new caller within 30 seconds. If you ignore the
signal, the waiting call is rejected after 30 seconds.
For instructions on how to turn the Call Waiting function on
and off, see the section “Call Waiting” on page 70.
Call Back on Busy (CCBS) on the ISDN Line
When you dial a number and it is busy, you can enable the
“Call Back on Busy” feature. As soon as the line is free, your
telephone rings for 20 seconds, as it would for an external
call. When you pick up your handset, the number of desired
party will be dialed automatically.
“Call Back on Busy” can be used for both external and in-
ternal connections.
