  2. At the bottom of the page, check Enable the First Priority for VoIP SIP/RTP.
  3. By clicking this green icon, you can see the status and analysis graph of each phone call.

What is DiffServ code point?

Differentiated Services Code Point (DSCP) is a means of classifying and managing network traffic and of providing quality of service (QoS) in modern Layer 3 IP networks. It uses the 6-bit Differentiated Services (DS) field in the IP header for the purpose of packet classification.

What is class of service in networking?

Class of Service (CoS) is a way of managing traffic in a network by grouping similar types of traffic — such as email, streaming video, voice over IP and large document file transfer — together and treating each type as a class with its own level of network service priority.

What is a DSCP code point?

Differentiated Services Code Point (DSCP) is a means of classifying and managing network traffic and of providing quality of service (QoS) in modern Layer 3 IP networks. It uses the 6-bit Differentiated Services (DS) field in the IP header for the purpose of packet classification.

What is DSCP 46 in VoIP?

Many VoIP devices advertise the classification of network traffic with a DSCP header. The Differentiated Services Code Point (DSCP) header tells network switches to honor packets with high priority. Configure both inbound and outbound RTP packets with DSCP 46 if you can.

What is a differentiated services code point?

Within an IP packet header, the Differentiated Services Code Point (DSCP) defines a value from 0 to 63 that maps to a certain traffic classification. DSCP values are used within a network, based on the operator’s own policies, to determine the treatment of packets in router queues, routes of traffic flows and per-hop behavior (PHB).

What is the default DSCP value for a packet?

The standardized DiffServ field of the packet is marked with a value so that the packet receives a particular forwarding treatment or PHB, at each network node. The default DSCP is 000 000. Class selector DSCPs are values that are backward compatible with IP precedence.
