Mitel 4015 manual Using Mlpp, To make a precedence call

USING MLPP

Multi-Level Precedence and Preemption (MLPP) facilitates emergency communications for the military. MLPP enables authorized users to specify a precedence level when making a call, and to preempt calls with a lower precedence level.

To make a precedence call:

1.Dial the precedence access digit (a number between 2 and 9). Wait for dial tone to end.

2.Dial the appropriate precedence level digit (a number from 0 to 3, such as 1 for Flash). Note that if you have chosen a higher precedence level than you are authorized to use, the system either routes the call to an announcement or you hear an error tone.

3.Dial the ARS leading digit (if necessary) and the destination telephone number (for example, 7-555-1234). If the destination is idle, the phone will ring and you will hear the Precedence Ringback tone. If the destination is busy and preemption is successful, you will hear silence until the called party acknowledges preemption by hanging up. You will then hear the Precedence Ringback tone. The preempted parties will hear the Preemption tone.

4.If the destination is busy and preemption is unsuccessful, you will receive a Blocked Precedence Announcement (BPA). If you get BPA, hang up and then retry the call at a higher precedence level if you are authorized to do so. If you get BPA and cannot retry the call at a higher precedence level, you can call MLPP attendant and ask the attendant to place the call for you.

5.Once you are connected, carry on your conversation. During the call, your telephone set will display both the precedence of the call and its duration.

6.When you finish the call, hang up.
