Official FPL guidelines you can find at: http://support.freephoneline.ca/entries/23120323-VoIP-Unlock-Key-Credentials
All the settings were default on the device before configuration.
Step 1.
Plug all the appropriate wires to your Grandstream HT502 device.
• Internet cable [Note: Connect Ethernet cable to WAN port of your Grandstream HT502 device and
another end to your Internet rack/router]
• Phone line (attached to the phone) [Note: Use Phone1 port]
• Power
Step 2.
By default settings Grandstream HT502 WAN access is disabled.
You have to enable this setting before you access web-based utility.
From the phone attached to Grandstream HT502 device:
• Dial ‘***’ (to access IVR menu)
• Then dial ‘12’ (to check your WAN Port Web Access status)
• Then press ‘9’ (to toggle between enable/disable) [Note: Your WAN Port Web Access should be enabled]
• Hang up the phone
Now, you have to figure out IP address to access web-based utility. From your phone dial:
• ‘***’
• Then dial ‘02’
Write down your IP address.
Step 3.
On the PC/Mac connected to the same network as your Grandstream HT502 device, go to your browser
(Internet Explorer; Chrome; Firefox; Opera; Safari, etc.).
In the URL bar put your IP address from Step 2.
[Note: I am using 192.168.23.95 for my IP, your IP address might be different!]
Web-based utility will appear.
Now you have to login.
