Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Calls not connecting | Network issues, SIP registration failed, firewall blocking | Check network connectivity, verify SIP credentials, review firewall rules |
| One-way audio | NAT traversal issues, incorrect RTP settings | Configure STUN server, check NAT settings, verify RTP ports |
| Poor call quality | Network congestion, QoS not configured, codec mismatch | Implement QoS, check bandwidth, ensure codec compatibility |
| Dial plan not working | Syntax errors, context issues, pattern mismatch | Review dial plan syntax, check context permissions, verify patterns |
| Registration failures | Authentication errors, server unreachable, expired credentials | Verify username/password, check server status, renew credentials |
| Call drops | Network instability, SIP timeout, keepalive issues | Check network stability, adjust SIP timers, configure keepalive |
