Answering a ringing call
•
Initiating off-hook dialing of a new call
•
Starting a new call by on-hook dialing or calling from speed dial, phonebook, or call history, etc.
Right before carrying out a foregrounding ope
ration, the phone automatically applies the following “backgrounding”
operations on all other calls in the system based on their respective call states at that moment:
•
Calls in Connected State: hold them
•
Calls in Ringing or Holding State: leave them alone
•
Calls in other states: end them
Call Waiting
Call Waiting refers to when there are one ore more new incoming calls while there are one or more calls in the other
states. If call waiting is disabled, all the new incoming calls are rejected as busy. If call waiting is enabled, incoming calls
will ring the phone if there are no connected calls. Otherwise the phone will play the call waiting tone.
Call Transfer
Transferring a current call with remote party A on the phone involves 1) calling another remote party B known as the
transfer target
and 2) connecting A and B while the phone user himself drops out of the conversation. Remote party A
is known the
transferee
while the local OBi1000 user is the
transferor
. There are three types of call transfer:
1.
Attended Call Transfer
: In this case, the OBi user waits for B to answer and talks to B first before completing
the call transfer. The OBi user presses the "Transfer Now" soft key to complete the call transfer. This is sometimes
called consulted transfer or transfer with consultation. Whereas the two types described below are sometimes known
as transfer without consultation.
2.
Semi-Attended Call Transfer
: In this case, OBi user waits for B's Phone to ring but before B answers to
complete the call transfer. The OBi user presses the "Transfer Now" soft key to complete the call transfer.
3.
Unattended (or Blind) Call Transfer
: In this case, the call transfer is completed by the phone as soon as the OBi
user enters B's number, without waiting for it to ring. That is, the OBi user does not need to press any additional key to
complete the call transfer. The OBi user would not know if B is busy, or if the number entered is valid or not.
To transfer a call, user must first identify the call to transfer by highlighting the corresponding entry in the call list of the
Calls App. Hence the Calls App must be running on the top of the screen at the first level. The call must also be in a
transferrable state, which is either the Connected or Holding state. If the highlighted call is transferrable, the soft keys
include the "Transfer" and "Blind Transfer" options. Select the "Transfer" option to perform an attended or semi-
attended call transfer, or select the "Blind Transfer" option to perform a blind call transfer. Below is an example of a
connected call with the Transfer and Blind Transfer soft keys shown.
