Call Origination Busy
When Call Origination Busy is enabled, incoming calls are prevented from
disturbing you when you are in the process of making an outbound call.
When your IP Deskphone is on-hook or off-hook and you enter the first
digit or character, then any call that comes in during the entry sequence is
not presented to you.
Incoming calls are shown when you cancel the outbound call by pressing
Goodbye, or when you place the receiver on-hook and the IP Deskphone
goes back to the idle state.
If you place an outbound call, and that outbound call rings or receives a
busy signal, any incoming call that was not presented is then presented.
Note:
The outgoing call cannot be preempted by any call until the
outgoing call rings or receives a busy signal.
The following sections describe Call Origination Busy behavior in various
