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:
• you complete dialing your call and ring or busy signal is heard. The incoming call is
presented if 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
presented if the incoming call has not hung up. You can decide to answer the call.
Incoming call while dialing outbound number + held call with priority higher then
incoming call
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.
Your dial pad entry sequence is not interrupted. Since the incoming call is of lower precedence
than the held call and you are entering digits for another call, the incoming call is sent a busy
response. The caller sees a User is Busy message.
Note:
The held call and the process of placing the second call are counted as two consumed call
appearances.
