Jitter buffers help smooth uneven data flow. Set these in your phone system’s admin panel. Wired connections beat WiFi for stability—use Ethernet cables whenever possible.
Quality of Service (QoS) Settings
Think of QoS as a traffic cop for your network. It lets voice packets skip ahead of less urgent data. Modern routers simplify this setup:
- Access router settings via 192.168.1.1
- Locate QoS/Network Priority section
- Assign highest priority to SIP/UDP ports
“Proper QoS configuration reduces call drops by 70% in congested networks,” says network engineer Laura Simmons.
Consistency matters—apply these rules to all switches and access points. While QoS won’t boost your internet plan’s limits, it ensures available bandwidth serves critical communications first.
Troubleshooting Common VoIP Issues
When your calls start cutting out or sounding robotic, quick fixes often restore clarity. Most audio glitches stem from network hiccups rather than service flaws. Let’s break down solutions for three frequent challenges.
Diagnosing Audio Problems
Echoes or choppy voices usually mean network congestion. First, check your router’s Quality of Service (QoS) settings. Prioritize voice traffic over other data like video streams.
Try these steps:
