Which DSCP value must be selected to mark video traffic between two Cisco 8845 phones?

DSCP value 24 corresponds to CS3 (Class Selector 3), which is typically used for less critical data traffic.

DSCP value 32 corresponds to CS4 (Class Selector 4), often used for bulk data or network control traffic, not primary video.

According to Cisco's Quality of Service (QoS) recommendations for video conferencing traffic, including video from IP phones like the Cisco 8845, the appropriate DSCP value is AF41, which corresponds to a decimal value of 34. This ensures video traffic receives proper prioritization over the network.

DSCP value 46 corresponds to EF (Expedited Forwarding), which is specifically reserved for real-time voice traffic due to its strict latency and jitter requirements.
