WAN QoS Configuration Example

This section provides a configuration example on setting up WAN QoS to give the voice traffic a higher priority for a phone system or the SPA phones through the security appliance.

Use Case: An IP phone is connected directly to the voice switch behind the security appliance or the LAN port the security appliance. Both voice and data traffic is sent out through the WAN port of the security appliance.

			192.168.75.1
IP	10.1.1.1	192.168.75.200	Internet
IP Phone	Vioce Switch		ISA500
(10.1.1.11)

Solution: For the voice traffic from LAN to WAN (outbound voice traffic), make sure that the outbound voice traffic is handled by the highest priority queue (Q1) and other outbound traffic such as data traffic is handled by the lower priority queues (Q2 to Q6). For the voice traffic from WAN to LAN (inbound voice traffic), CoS and DSCP will be remarked so that the voice switch can prioritize the inbound voice traffic by incoming CoS or DSCP.
