0 min
1\ login to webclient then go to the admin panel (not the classic management console) 2\ edit your extension, and delete the phone from there there should be no phones left on this extension 3\ add the model model again (router phone > x4u v2) and make sure you enter the mac correctly 4\ once you see new credentials on the screen, you must factory reset the phone (hold the ok button until you see the factory reset option, then confirm) 5\ when the phone reboots, it might stay idle for 1 2 min at most, and it will then ask you for those credentials make sure that when you enter them, you pick the "123" mode on the keypad, not the "abc" mode once the credentials are entered it will provision and then reboot automatically the phone should now be successfully provisioned and should not disconnect from 3cx no matter how much time passes you may now also edit your other phones on that same network and select this device as their sbc (if needed) the phones will need to be rebooted so they can pull the new provisioning from 3cx telling them which sbc to use if you don't have other normal phones at that same location then this bit is not needed
