If the number of a subscriber is busy and your call is urgent, instead of continually dialing
the number, you can activate an automatic call-back “when busy“ (CCBS: Completion of
Calls to Busy Subscriber). The subscriber being called must also have this technical
capability. When the connection is no longer busy, your smar-tel-i will ring. When the
receiver is picked-up, the telephone number is displayed and automatically dialed. Then the
subscriber‘s telephone rings.
For internal subscribers, a call-back can be initiated for “when no response“ and “when
busy“. Both parties are then simultaneously called by the call-back.
Example: Initiate a call-back for a subscriber that is momentarily busy.
Example: Call-back as soon as the subscriber has replaced the receiver.
h
An external call-back (CCBS) is stored for approximately 45 minutes and then
deleted. An internal call-back is stored indefinitely in the PBX.
The costs for the call-back which you initiated are debited to your connection.
If you do not accept a call-back it is deleted.
If you do not wish to accept a call-back, then press the soft-key under “end“ or exit key
e
. The call-back is deleted.

If you do not operate your smar-tel-i with an AUERSWALD PBX, but rather connect it
directly to the network termination of your EURO-ISDN interface, then only the follo-
wing text can be generated in the above examples: “user account active“, “blocked“,
and “dialing blocked“. This is because smar-tel-i itself generates this text and not the
PBX.

Initiating a Call-Back
Call back
A
Activate automatic call-back.
An audible confirmation can be heard and you
can replace the receiver. (If you do not hear
the audible confirmation, the call-back has not
been activated.)
c
b
Prefixed with “call-b“, the number to be called-
back appears in the top display line.
If you do not operate your smar-tel-i with an AUERSWALD PBX, but rather connect it
directly to the network termination of your EURO-ISDN interface, then instead of an
audible confirmation, you will receive the message “Entry“ in the display.
For a call-back, instead of “call b“ an “r“ precedes the call-back number in the display.
Up to three call-backs can be initiated and can also be individually deleted. (Refer to
the chapter Deleting Call-Back “When busy“ on page 57.)
