Call and transfer
Description of operation and display under CallDepending on the situation or personal preference, calls can be made using the handset, the integrated microphone/speaker or a headset (optional accessory).
Note: In permanently noisy environments, it makes sense to switch off the sidetone in the handset (in the phone:Settings > Sound > Handset sidetone). The volume is automatically increased.Hands-free calling mode
During hands-free calling, the loudspeaker and microphone on the device are switched on. This enables you to phone if you don't have a hand free. Other people in the room can take part in the call.
Description of the operation under Hands-Free CallingLoudspeaker listening mode
In loudspeaker listening mode, both the loudspeaker in the receiver and the loudspeaker in the device are switched on. This enables other people in the room to listen in on the call. The call is continued using the microphone in the receiver (not hands-free operation).
Description of the operation under Loudspeaker listeningHeadset mode
A headset enables you to participate in calls without actually holding the receiver, unlike when you use a receiver. Corded and cordless headsets are supported. Headsets that are connected to the telephone are prioritised as follows:
1.Bluetooth headsets
2.USB headsets
3.Headsets with a DHSG interface
Note: Only connect one USB headset.Caution: When using a Bluetooth headset, make sure that the telephone is disconnected from the power supply before plugging in the COMfortel D-Wireless (EZC-5200BS).Note: To connect an USB headset, only use the USB sockets provided for this purpose on the telephone and not on the COMfortel D-XT20/D-XT20i key extension module.A headset must be plugged in for these functions to work:
•Initiating headset calls
•Transferring an active call to the headset
•Ending a call in headset operation
•Initiating the listen-in function on the receiver
•Ending the listen-in function through the receiver
Description of the operation under Headset CallQuery Calls
During a query call you are talking with one subscriber while the previous call partner is put on hold by the PBX in the background, and hears the on-hold music.
The phone supports 3 call channels. When the channels in the phone are put on hold in the PBX, they become inactive, so up to 2 calls can be on hold in addition to one active call.
A query call is initiated either by calling a query call subscriber, by picking up during a call, or by accepting a call signalled by the audible indication.
During a query call, the following options are available.
•Splitting a call: You can use the transfer function to alternate between the call partners.
•Ending one of the two calls: When you end a query call and would like to continue talking with one of the call partners, you can end the call with the other call partner separately. Alternatively, one of the call partners can simply hang up so that you can continue talking with the other call partner.
•Connecting the two call partners to each other: If you would like to let your call partners speak with each other, you can connect them.
Note: In order to connect two external call partners, the authorisation "Transfer of external calls to external" must be granted in the PBX.Consult the PBX manual for this.Description of operation and display under Query CallsTransferring calls
During an existing call, you can perform a call transfer in these ways.
•Transfer the call with an announcement: A query will be initiated. The call is announced and both call partners are then connected.
•Transfer the call without announcement (blind transfer): The transfer destination is dialled and hung up while the call is still being rung. As soon as the person called answers, the connection is established. If the person called does not answer, the call goes back to your own phone (the phone rings).
•Calling a 3rd internal subscriber and connecting them to an active call partner: Another call is added to an existing call (e.g. by answering a waiting call). This second call partner should be transferred. To do this, a third call is initiated and the second is connected to the third call partner. The original, existing call continues.
Note: In order to connect two external call partners, the authorisation "Transfer of external calls to external" must be granted in the PBX.Consult the PBX manual for this.Description of operation and display under Transferring callsConference call
During a conference you speak to two call partners at the same time.
All the options listed above are for a conference call that you have initiated yourself.
•Splitting a call: During a conference, you can alternately speak to one of the two call partners and deliberately push the other into the background. You do not have to end the conference call, to do so.
•Connecting both conference partners to each other: If you want to leave a conference call, but the conference call partners would like to continue talking with each other, you can connect the two parties with each other.
Note: In order to connect two external call partners, the authorisation "Transfer of external calls to external" must be granted in the PBX.Consult the PBX manual for this.•Splitting a conference: The conference call is cancelled. One caller is on hold and there is an active connection with the other caller. You can change between holding a call and an active call.
•Holding a conference call and initiating an additional call: The entire conference call is held. The conference call partner hears music on hold. When the call ends, the conference call can be continued.
•Ending a call with a conference partner: You can end the conversation with one conference partner and then continue speaking with the remaining caller. This also applies if one of the conference call partners hangs up.
•Ending a conference call completely: If you initiated the conference call, you can end the conference call completely.
