1. Grandstream GXW Not Working After Setup

What’s Going On?

In some cases, after everything is set and done, after initial setup, you might find your Grandstream GXW not working at all, like no dial tone, no lights, and no signal.

Why It Happens:

• Improper power connection.
  
• Firmware glitches.
  
• Incorrect VoIP settings.
  
• Internet issues.

How To Fix It Fast:

• Double-check that the power cable is securely connected.
  
• Restart the device (yep, that good or’ “turn it off and on” trick still works).
  
• Make sure your internet connection is stable.
  
• Log in to the web UI (user interface) and verify SIP settings.
  
• If all else fails, update the firmware from Grandstream’s official website.

Tips: Always use the power adapter that came with the device. Third-party power sources can cause boot failures.

2. Registration Fails – No SIP Connection

What’s Actually Happening? 

You’ve connected your entire setup, but your analog phones won’t register on your VoIP system. You might see messages like “SIP registration failed” or “account not registered.”

This Is One of the Most Grandstream GXW Configuration Issues

Reason It Happens:

• Incorrect SIP server address.
  
• Wrong SIP port.
  
• Firewall or NAT is blocking the connection.
  

Quick Fix That Works:

• Log in to the web interface.
  
• Check the SIP server IP or hostname under “Accounts > General Settings.”
  
• Confirm the port number (usually 5060 for SIP).
  
• Make sure any firewalls or routers aren’t blocking ports needed for SIP traffic.
  
• Enable STUN (Session Traversal Utilities for NAT) if you’re behind a NAT.

Why It Happens:

• NAT/firewall issues.

• Low bandwidth.

Quick Solutions:

• Log in to your router and make sure RTP ports (usually 10000–20000) are open.
  
• Under “Advanced Settings,” enable NAT traversal.
