Correct way to config Grandstream GXW4104 and cloud 3cx install

[windsoft-br]

Hello guys,

I have an environment with a Grandstream GXW4104 and 4 analog phone lines.
My 3CX server is in the AWS cloud and the SIP trunk is local.
Sometimes the SIP trunk shows a red circle and I can't make calls, but I can receive. To Fix it, I need to restart Grandstream.
I think it's because I didn't configure it correctly.
What is the correct way to configure this environment?

Hello @windsoft-br

Please note that your current configuration is not supported and I am surprised it even works as good as it does.
The correct way would be either to use a SIP trunk provider and move away from analog phone lines or move your PBX locally to where your gateway is.

Depending on what the Activity Log suggests the issue might be, and you don't want to spend the time attempting to resolve, and how often this occurs, you might consider this...

Plug in the gateway to a digital timer, that is set to turn the device off, for one minute, then back on, at some point before office hours begin. It's a bit crude, but might allow you to make calls though the day without having to do this manually.
