The service that you would implement at your edge device to prioritize VoIP traffic in this scenario is AppQoS. AppQoS is a feature that enables you to allocate bandwidth and prioritize traffic based on application signatures or custom rules. AppQoS can enhance the quality of service and experience for critical or latency-sensitive applications, such as VoIP. You can configure AppQoS policies to assign different classes of service (CoS) values or queue numbers to different applications or traffic flows. You can also define bandwidth limits, guarantees, or bursts for each class or queue.Reference:= [Application Quality of Service Overview], [Configuring Application Quality of Service]

static attack object groups are predefined groups of attack objects that are included in Juniper's IPS signature database.These groups do not change automatically when Juniper updates the database2.

The early-ageout configuration specifies the timeout value, in seconds, that will be applied once the high-watermark value is met. The high-watermark configuration specifies the percentage of how much of the session table can be allocated before applying a more aggressive age-out timer. This ensures that the session table does not become full and cause traffic issues, and also ensures that existing flows are aged out quickly when the table begins to get close to being full.

The two tasks that must be completed before a configuration for IPS on an SRX Series device will work are downloading the IPS signature database and installing the IPS signature database. The Security, Specialist (JNCIS-SEC) Study guide provides further information on how to download and install the IPS signature database. Enrolling the SRX Series device with Juniper ATP Cloud is not necessary to make a configuration work, and rebooting the SRX Series device is not required either.

AppQoE is a feature that enables you to monitor and optimize the quality of experience for applications on your network. It uses application-aware routing and dynamic path selection to choose the best path for each application based on predefined or custom SLA profiles. AppQoE also provides visibility and reporting on application performance and network conditions. Two requirements for enabling AppQoE are:

You need two SRX Series or MX Series device endpoints: AppQoE can be configured between two SRX Series device endpoints or between an SRX Series device and an MX Series device in a hub-and-spoke or full mesh topology. The devices must run the same version of Junos OS and have the same AppQoE configuration.

You need an APPID feature license: AppQoE requires an APPID feature license to be installed on the SRX Series device. The APPID feature license enables application identification and classification, which are essential for AppQoE to work.
