Don’t always believe what you read on the internet! I find a lot of wrong answers on these test sites.
In my courses, all I have heard about VoIP is it uses RTP, SIP, PoE, and QoS

An application level gateway is a firewall that is capable of filtering based on information contained within the data portion of a packet. An application level gateway:
Examines the entire content (not just individual packets).
Operates at OSI Layer 7 (Application layer).
Understands or interfaces with the application-layer protocol.
Can filter based on user, group, and data such as URLs within an HTTP request.
Is the slowest form of firewall because entire messages are reassembled at the Application layer.
One example of an application level gateway is a proxy server. A proxy server is a device that stands as an intermediary between a secure private network and the public. Proxies can be configured to:
Control both inbound and outbound traffic.
Increase performance by caching heavily accessed content. Content is retrieved from the proxy cache instead of being retrieved from the original server.
Filter content.
Shield or hide a private network.
Restrict access by user or by specific Web sites.
