Purchased a Grandstream telephone adaptor?
If you have purchased a Grandstream telephone adaptor (ATA), it will come configured for the US telecom system as standard. As such, it will play back US style tones, sounds and some UK phone features may not work correctly unless you make some configuration changes via the devices web based GUI.

What are the UK regional settings for the Grandstream telephone adaptors and how do I implement them?
Login to your Grandstream telephone adaptors web based GUI by typing the IP address of the device into your web browser. (There is no need to enter "http://" before the IP address.) If prompted enter the username and password to complete the process, you should now have access to the devices Web based GUI, from here you can configure your device with the correct regional configuration settings for use in the UK.

As an example, on the Grandstream HT812 configure with the following:
  • Navigate to the BASIC SETTINGS page:
