Answer

To optimize your network for better VoIP call quality, focus on minimizing latency, jitter, and packet loss while ensuring sufficient bandwidth. Implementing Quality of Service (QoS) policies and using VLANs can help prioritize VoIP traffic and reduce interference from other types of data.

Identify and classify VoIP traffic using DSCP markings or VLAN tags to distinguish it from other traffic types.
Implement QoS policies on routers and switches to prioritize VoIP packets, ensuring they receive higher priority over less critical traffic.
Configure traffic shaping and policing to manage bandwidth allocation and prevent congestion on network links.
Use network monitoring tools to analyze traffic patterns and identify any bottlenecks or areas of packet loss.
Regularly test and validate call quality using tools like MOS (Mean Opinion Score) to ensure optimal performance.

Additional Comment:

Ensure that your network devices support QoS and are properly configured to handle VoIP traffic.
Consider using separate VLANs for VoIP to isolate voice traffic from data traffic, reducing potential interference.
Regularly update firmware on network devices to benefit from performance improvements and security patches.
Use redundant network paths and failover mechanisms to maintain call quality during outages.
