Description (partial)

Symptom:
1. Configure the following Enterprise Paramaters:
MLPP Indication Status Required Field - MLPP Indication Turned On
MLPP Preemption Setting Required Field - Forceful Preemption
2. Add a translation pattern for MLPP calls and set MLPP Precedence to Executive Override
3. Place a non-MLPP call to a TNP phone and let it ring
4. Place a 2nd call using the MLPP translation pattern to the same TNP phone and let it ring
5. On the TNP display, you should notice the MLPP call has the 4 boxes next to it and it is highlighted.
6. Answer the MLPP call with the Answer softkey.
7. Hang up the calls and place them again in the same order.
8. This time on the TNP display, the MLPP call will still have the 4 boxes but it is not highlighted. When the answer softkey is pressed, the non-MLPP call is answered because it has the focus.
9. Reset the phone and place the calls again. The first time, the MLPP call will correctly be given the focus but on every subsequent call, it will not have the focus until the phone is reset again.
