Troubleshooting Yeastar SIP trunk is crucial for ensuring your phone system operates optimally. Common issues include trunk being offline, no incoming calls, one-way audio or RTP problems, and NAT-related questions. By using Yeastar Event Log and SIP-debug, you can effectively identify and resolve these issues.

Check Trunk Status in Yeastar Dashboard

  1. Step 1: Log in to Yeastar Dashboard

    Use your credentials to log in to the Yeastar Dashboard.

  2. Step 2: Go to SIP Trunk Settings

    Navigate to the SIP trunks menu and click on the trunk you want to check.

  3. Step 3: Check Trunk Status

    Check if the trunk status is "Registered". If the trunk shows "Offline" or "Registration Failed", there are issues that need to be resolved.

Trunk Shows Offline or Registration Failed

  1. Step 4: Check SIP Credentials

    Ensure all SIP credentials (username, password, server address) are correct. You can find these on portal.internetport.com -> Services -> My Services -> [SIP Trunk] -> Configuration Details.

  2. Step 5: Check Server Address and Ports

    The SIP server for Internetport is sip.internetport.se. Make sure the correct ports are used: UDP on port 5060 or TLS on port 5061.

No Incoming Calls Despite Registered Trunk

  1. Step 6: Check DID Settings

    Ensure DID numbers (Direct Inward Dialing) are correctly configured in Yeastar and match the numbers you have with Internetport.

  2. Step 7: Check Incoming Routes

    Ensure incoming routes are correctly set up to direct calls to the right internal lines or queues.

One-Way Audio or No Audio (RTP)

  1. Step 8: Check Codec Settings

    Ensure the codecs used are compatible with Internetport. Supported codecs are G.711 a-law (PCMA), G.711 u-law (PCMU), G.722, and G.729.

  2. Step 9: Check RTP Ports

    Ensure RTP ports are correctly configured and open in the firewall if necessary.

NAT-Related Issues

  1. Step 10: Enable STUN Server

    Use Internetport's STUN server stun.internetport.se to handle NAT issues.

  2. Step 11: Check NAT Settings in Yeastar

    Check the NAT traversal settings in Yeastar and ensure they are correctly configured.

Enable and Read Yeastar Event Log and SIP Debug

  1. Step 12: Enable Event Log

    Navigate to the Event Log menu in Yeastar and enable logging.

  2. Step 13: Analyze Event Log

    Analyze the event log for error messages or warnings that may indicate trunk issues.

  3. Step 14: Enable SIP Debug

    Enable SIP debug in Yeastar to get detailed information about SIP messages. This helps identify communication problems between Yeastar and Internetport's SIP server.

Check NAT Settings and Local IP Address

  1. Step 15: Check Your Local IP Address

    Ensure your local IP address is correctly configured and there are no duplicate conflicts.

  2. Step 16: Check NAT Settings on Router

    Check the NAT settings on your router to ensure ports are correctly opened and forwarded to the Yeastar device.
