Configure a SIP Trunk on a DYNASTART MTG200

To configure a SIP trunk on a Dynastar MTG200, you'll need to access the device's web GUI and configure the SIP trunk settings. This involves setting the IP address, registration details (if required), authorization data (username and password), and other parameters like codecs and DTMF settings. 

1. Access the Web GUI:
  • Open a web browser and enter the MTG200's IP address in the address bar. 
  • Log in using the default username and password (usually "admin" and “admin@123#) or the credentials you set during initial configuration. 
  • The default IP is 192.168.11.1

 

2. Navigate to SIP Trunk Settings:
  • Locate the "SIP Trunk" or "Trunk" settings within the web GUI. 
  • The exact location may vary depending on the MTG200's firmware version, but it's typically under SIP Config "SIP Trunk".
 
3. Configure Basic Information:
  • Name: Give the SIP trunk a descriptive name for easy identification. 
  • Trunk Status: Enable the SIP trunk. 
  • ITSP Template: Select "General" or a relevant template if available. 

 

 

 
4. Apply Changes:
  • Save the changes by clicking the "Apply" or "Save" button. 
5. Testing:
  • After applying the changes, test the SIP trunk by making and receiving calls. 
Troubleshooting:
  • Firewall: Ensure that your firewall rules allow traffic between the MTG200 and UnitedCloud. 
  • IP Conflicts: Verify that the MTG200's IP address does not conflict with other devices on your network. 
  • Codecs: Ensure that the codecs are compatible between the MTG200 and UnitedCloud.
