Telephoning 15
During a call different situations may occur e.g. you like to ask another
person to this conversation issue or another caller tries to reach you.
You are not forced to finish the current call to react to these circum-
stances, you will be able to put this call on hold in the PBX or to park it
for a short time period.
Query Call:
If you like to ask a question to somebody during a call with-
out finishing the conversation, use the Query. The current conversation
is put on Hold in order to call the other subscriber. The 1st calling part-
ner is on Hold in the background in the PBX and listens to the Music on
Hold.
In order to start a Query in case of DTMF telephones or ISDN tele-
phones, you will have to press the FLASH key or R-key first (see chap-
ter Differences using various Telephones on page 9). Then you will
hear the internal dial tone as after picking up the receiver and you can
start a call as usual.
Pickup:
If you hear an internal telephone ringing, while you are just hav-
ing a call, you are able to put the current call on hold by the PBX, in
order to accept another call. For this purpose you use a function that is
called „Pickup“. With this function you transfer the call to your telephone
by dialling a sequence of digits.
Muting a Call (with DTMF-Telephones):
If you like to make a call with
a DTMF telephone it will be possible to interrupt it for a short period in
order to ask a question into the room. Simply press the FLASH key. You
will hear the internal dial tone then. Your calling partner is on hold in the
background and listens to the Music on Hold during this time. In order
to continue the call, press the FLASH key again.
Parking external Call:
If you have an external call and like to interrupt
it for a short time, you are able to park it with the function „Parking/Ter-
minal Portability“ up to 3 minutes in the public exchange. If you like to
change the room during the parking, you are able to unpark the call with
any other internal telephone again. The call has to be unparked within
3 minutes otherwise it will be disconnected by the public exchange and
you will hear the busy tone while you are unparking.
You are also able to park or unpark the call with an ISDN device that
you are using in parallel to the PBX on the same NT (see operation
manual of the corresponding device). Some of these ISDN telephones
are not able to takeover a parked call without a parking code. If you use
such an ISDN telephone on a Point-to-Multipoint connection in parallel
to the PBX, you can instruct the PBX via program function to park calls
onto the bus always with a parking code (see chapter You like to park
Calls with a Parking Code on page 47).
Parking a Call on the internal S
0
Port: If you have a conversation with
an ISDN telephone (internal subscriber) on the internal S
0
port and like
to interrupt it for a short moment, you will be able to park it on the inter-
nal S
0
port with the function „Parking/Terminal Portability“ up to 3 min-
utes. How to execute this function on your ISDN telephone is to be
learned in the operation manual of the corresponding telephone. This
function is often called Parking/Terminal Portability (TP). A parking
code number will be ignored by the PBX and is harmless.
If you like to change the room during the parking period, you will be able
to pull out the ISDN telephone of the wall jack and put it into another wall
jack of the same S
0
bus. The call has to be unparked by an ISDN tele-
phone on the same internal S
0
bus within 3 minutes, otherwise it will be
disconnected.
The chapter You have two Calls (Query Call) on page 19
describes the options for query calls.
How to accept/take/reject a waiting caller, can be learned in the chapter
Call Waiting Tone in the Receiver on page 10.
During a door terminal call a Query is not possible. In contrast
to that, you are able to start a door terminal call from within
another call.
On a Direct Exchange Line Telephone you hear the internal dial tone
after pressing the FLASH or R-key. The operation in this case is the
same like for the other telephones.
On ISDN telephones and on the system telephone the
„Query“ is started via an existing function key or via menu
(e.g. with „Call2“, „Query“, „on hold“ or „R-key“; see manual of the tele-
phone).
If you use an analog telephone as an internal subscriber tele-
phone, where you can start a „Query call“ via T-Net function
