1. Caller A, Flash (oldest or first coming)
2. Caller B, Routine (next oldest or second coming)
3. Caller C, Routine (third oldest or third coming)
4. Caller D, Priority (newest or just coming)
The calls are presented in the following order.
1. The call from Caller A is displayed first, since it has the highest precedence of all
incoming calls.
2. If Caller A’s call is answered, then the call from Caller D is displayed using the other
free call appearance, since it has the second-highest precedence of B,C, and D.
3. If Caller D’s call is answered, then the call from Caller B is displayed, since it is the
most recent (if Call A has ended. If not, Caller B hears a Busy signal, since call
appearances are limited to two.)
4. If Caller B’s call is answered, then the call from Caller C is displayed (if Caller D has
hung up).
Preemption
Only two simultaneous calls can be presented. If your IP Deskphone reaches the maximum
call limit and you receive a higher precedence call, then one of the existing calls is preempted
in order to present the higher precedence incoming call. An incoming call with a precedence
level less than or equal to the already-received call precedence levels is not presented.
Note:
Emergency 911 calls can be preempted when there are no available call appearances and
there is an incoming above-Routine precedence call.
IM sessions cannot be preempted because they do not count as a call appearance.
Order of call preemption
The following is the order of call preemption:
1. the lowest precedence call
2. If there are multiple calls on the same precedence level, then the following order is
used:
a. any outgoing call that is unanswered
b. the oldest incoming call that is unanswered
c. the oldest held call
