Hi guys, I updated my 3CX to the last version and noticed the Grandstream phones were back in business. So I updated the firmwares and deleted my custom templates to use the built-in one. Now I have a big problem: my remote phone keeps ringing constantly. I tried disabling Direct IP Calls, I tried removing my NAT forwarding, and I tried "Accept INVITE only from Proxy" but these configuration gets overwritten on every provisioning. I don't want to use a custom template but I need it to stop ringing. It rings during the night now.
