Mission-critical application
Often, a VPN connection is a mission-critical application for exchanging data between Head and Branch offices.
This mission-critical application must be connected smoothly, without any dropping. To ensure this, you should set
the priority to the high level to preventing any other applications from saturating the bandwidth.

Voice applications are latency-sensitive. Most VoIP devices use the SIP protocol, which automatically assigns a
port number. This means that it is better to use a fixed IP address to catch VoIP packets and rout them as high
priority traffic.
