So the phone gets no part of the config or simply doesn’t register ?
I typically start here:
From SNG7 command line run the following and reboot the phone … watching the output of the below command
tail -f /var/log/httpd/access_log | grep -i sangoma
Is the phones request for the config actually making it the server ? If you don’t see it reaching the server try using the same config server info directly inputting it into phone
If neither of the above work call support Monday after opening a phone ticket and we’ll help
