Important: If you use an analog exchange line for the external call,
deleting callback is not possible.
Note: In case of an ISDN telephone direct dialling after taking the
receiver of the ringing telephone is not possible (instead of the exter-
nal dial tone you will hear the acknowledgement tone). Hang up the
receiver and pick it up right after that - now you can dial as usual.
Important: To start a “Recall on no Reply“ on ISDN telephones and
system telephones or to delete it again, this function must be sup-
ported via function key or via menu of the telephone (see manual of
the telephone).
Note: A recall is tried up to 45 minutes by the PBX. If the called per-
son did not finish his call until then, the recall would be deleted auto-
matically.
If you do not pick up the receiver in case of a recall in time (After you
have been called for 20 seconds), the recall will also be cancelled.
Important: To start a “Recall on no Reply“ on ISDN telephones and
system telephones or to delete it again, this function must be sup-
ported via function key or via menu of the telephone (see manual of
the telephone).
You can only use this function if the telephone service “recall on no
reply (CCNR)“ is offered by the network provider and has been acti-
vated.
The technical condition for a recall must be given e.g. the recall to a
PBX is not possible with some of the network providers. Also if using
a VoIP account or an analog exchange line for the external call, no
callback is possible.
Note: If you do not hear any acknowledgement tone, the recall
request was refused by the public exchange.
A recall is tried up to 45 minutes by the public exchange. If the called
person did not finish his call until then, the recall would be deleted
automatically.
If you do not pick up the receiver in case of a recall in time (After you
have been called for 20 seconds), the recall will also be cancelled.
Start Query Call: If you like to ask a question to somebody during a
call without finishing the conversation, use the Query. The current
conversation is put on Hold in order to call the other subscriber. The
1st call partner is on Hold in the background in the PBX and listens to
the Music on Hold.
In order to start a Query you will have to press the FLASH key or R-
key first (Exception: pulse telephone; see
). Then you will hear the internal dial
tone as after picking up the receiver and you can start a call as usual.
