How to setup basic MLPP ?
a. Take three phones 1025, 1026 and 1027. Let 1025 be the destination phone. 1026 be able to make Exec Override calls. 1027 be able to make Flash Override calls.
b. Set them all up in same MLPP domain 000011 (for ex:)
c. Set 1025 with MLPP indication enabled, Premption – Forceful
d. Set 1026 and 1027 with MLPP indication enabled, Premption – Can be disabled. No need to set them to forceful.
e. Create translation pattern 90.1025 in partition Exec and set the MLPP setting to Executive Override. This TP can be accessed only by 1026. Translate 90.1025 to 1025.
f. Create translation pattern 90.1025 in partition Flash and set the MLPP setting to Flash Override. This TP can be accessed only by 1027. Translate 90.1025 to 1025.
g. Place a flash override call from 1027 to 1025. (Dial 90.1025 from 1027.). You should note a different ring tone on 1025 and also a precedence ringer display.
h. Place a exec override call from 1026 to 1025 (Dial 90.1025 from 1026). You should immediately hear a precedence tone on 1025 and 1027. (Continous tone). Both parties 1025 and 1027 have to independently hangup. The Exec override call from 1026 is offered to 1025. Phone 1025 starts ringing.
i. If 1025 doesnt answer the exec override call from 1026, after 30 seconds, the call between 1025 and 1027 is dropped and the exec override call from 1026 is offered to 1025.
j. A flash override call cannot preempt a exec override call. If 1026 and 1025 are in a exec override call, a flash override call from 1027 cannot preempt the call between 1026 and 1025, as the flash override call has lower precedence. The flash override call will appear as call waiting on 1025. (No call waiting beep is heard).
k. An exec override call cannot preempt another exec override call (same domain), unless the service parameter Exec Override Call Preemptable is set to true. With the default setting (false), if 1026 places an exec override call to 1025, and 1027 places an exec override call to 1025, this call will appear as call waiting on 1025. (No call waiting beep is heard).
l. Do not set Preemption enabled to Forceful and Premption indication to Off of Default (If device pool is also off). This will prevent preemption on the destination device.
m. Only calls originating from devices in same domain can be prempted. If 1026 is set to domain 000011 and 1027 is set to domain 000022, 1026 cannot override 1027's call and vice versa.
n. If both 1026 and 1027 are set to flash override, One flash override call cannot preempt another flash override call. The call appears as call waiting (no beep is heard)
