Extensions unregistering and registering

Hi, I also have the same problem and described it in details (with logs and configuration) in this thread enter link description here I have one question to @dolesec if I downgrade an Asterisk version by this way, will I be able to update to a newer version in the future? I mean, could I use the upgrade scripts provided by FreePBX in the future? I’m afraid that maybe something will be broken in automatic update functionality.
