Set up AS-SIP
Depending on how you have configured your phone system, you may be able to make priority calls using the
Assured Services for SIP Lines (AS-SIP) feature.
With this feature, routine calls are placed normally. However, during an emergency, you can select a priority
level that helps ensure the delivery of critical calls. Depending upon how your phone is configured, you may
have to sign-in also.
When you receives a priority call, a precedence level icon displays next to the caller's name on your phone.

• MLPP Preemption: Determines whether preemption for reuse can be performed on the device. This type
