Troubleshoot Grandstream Phones

Hi, I am Alejandro at Voiceopia, and I am going to teach you how to troubleshoot your new Voiceopia phone.
The very first thing I like to check is that the device is getting power. This may be through a power cable that looks like this or it may be on the same line as your internet connection. If you only have an internet cable plugged in and are not sure if it is being supplied power check a working phone around you to see if it is using a separate power adapter.
Once we have established the phone has power, let's see what's going on. If you get an error message that say "No Lan Cable" this means your phone does not have a connection to your network. We can fix this by checking the cable plugged into the phone. The cable could be bad or the port on wall may not be connected. If you get an error message that says "Network Down" this means the phone is connected to your network but it is not getting an address from a router. This could be in the case that your router is down or you need special network settings to connect to your network.
If you get the error message "account not registered" or "no response" or you see that your lines are red and you are not able to make a call. This indicates that your phone does not have an active connection to the internet. I would first make sure that other devices on the network are connected to the internet. If the internet is down then I would start there first. If there are devices connecting to the internet but the phones are still not working I would try plugging a different device into the same cable as the phone and see if it can connect. If not then that would suggest the cable or wall port is bad. If the separate device does connect then I would suggest giving us a call to make sure your location is whitelisted and we can continue troubleshooting it from there.
