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. An example is shown in the following
figure.
Figure 87: User is Busy message
Note:
The held call and the process of placing the second call are counted as two consumed call
appearances.
Incoming call while dialing outbound number + held call with priority lower 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.
