We have a few customers who are using an HT802 for faxing and one of them started having issues. I went to upgrade the firmware manually from the web UI but Grandstream no longer allows it to be updated this way.

Is there way to push the firmware from 3CX like the IP phones? I can change the firmware server path but worry next time it checks for config from 3CX it will get overwritten.
