Troubleshooting
Common Issues
"Registration Failed" or "401 Unauthorized"
Double-check your username and password. The username is just the extension number (e.g., 100), not the full SIP address.
No Audio / One-Way Audio
Ensure your firewall allows UDP ports 5060 and 10000-20000 (RTP). If behind NAT, enable STUN with server stun.l.google.com:19302.
TLS Connection Fails
Make sure you're using port 5061 and the transport is set to TLS/TCP, not UDP.
