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 scenarios.
Incoming call while dialling outbound number + one free call appearance line
When you enter the first digit or character to make a new call, then any call that comes in during this
time is not presented. The incoming call hears ringback tone.
Your dial pad entry sequence is not interrupted. The incoming call is shown to you when:

the incoming call has not hung up. You can decide to answer the call.
• you decide to cancel dialling by pressing Goodbye or hanging up. The incoming call is
