1. The first thing to do is check your Internet.

Problem: Dropped calls, delayed voice, robotic voice.

Problem: An echo, static, or poor sound.

Solution:

Use noise-cancellation headsets to work perfectly.

Avoid Laptop built in mics they can capture background noise.

Turn off system enhancements or audio filters that warp your voice.

3. Network Security and Optimization

Solution:

Turn Quality of Service (QoS) on your router to provide priority to VoIP.

Forward or open SIP (port 5060) and RTP (ports 1000020000) so that there is a clear transmission of voice.

Avoid calling using the public networks, or wobbly VPNs.
