Prioritization
Use Quality of Service to maintain prioritization
Many devices support Quality of Service (QoS) tags to maintain traffic priority across the network. It is beneficial to tag your voice traffic with the appropriate tags, so it can be prioritized anywhere in the network in the event of a saturated link. This will help to prevent any audio issues caused by voice and data competing for the same bandwidth over your internet connection.
