The quality of VoIP routes depends on the networks carrying traffic. Choose routes with proven carriers that prioritize voice packets and avoid congestion. Optimize routing by selecting paths with the fewest hops, avoiding paths traversing the public internet. Monitor route quality and quickly remove underperforming routes. Implement direct peering relationships between networks and avoid transit carriers when possible. Use SIP trunks for call signaling redundancy. Invest in network infrastructure upgrades like more bandwidth. Shift to HD audio codecs like G.722 for clearer quality. With real-time analytics, identify and correct issues proactively. High-quality routes deliver reliable connectivity essential for VoIP call clarity.
