VoIP - Voice over Internet Protocol
The VoIP functionality enables telephone calls to be placed through your existing Internet connection
instead of going through the PSTN (Public Switched Telephone Network). It is not only cost-effective,
especially for long distance telephone calls, but also allows toll-quality voice calls to be placed over the
Internet.
After completing your VoIP configuration, remember to apply the changes,
SAVE CONFIG and restart to activate your VoIP functionality.

DSCP Marking: Differentiated Services Code Point (DSCP), it is the first 6 bits in the ToS byte. DSCP
Marking allows users to assign specific application traffic to be executed in priority by the next Router on
the backbone network, based on the DSCP value.
Note: To make use of this functionality, ensure that all of the routers in the backbones network have the capability of
executing and checking DSCP through-out the entire QoS network.
