- Check Internet Stability:
- Run a speed test to ensure your connection is stable and has sufficient bandwidth.
- Restart your router and modem.
- SIP Registration Issues:
- Log into the Yealink web interface and check Settings > Audio Codec.
- Ensure commonly used codecs like G.711, G.729, and Opus are enabled.
- Firewall/Router Issues:
- Some routers block VoIP audio while allowing SIP registration.
- Ensure SIP ALG (Application Layer Gateway) is disabled in your router settings.
- Test Another Network:
- If using WiFi, switch to an Ethernet cable connection.
- Try connecting the phone to another network to see if the issue persists.
