Today my Free 16SC license expired and now my management console shows my maintenance has expired. this means that now I am unable to download any updates for firmware, templates etc. I just bought a new GrandStream GXP2135 for testing and am unable to download the new firmware that is the "minimum required" version. I performed a forum search and found a thread where somebody was advised that there was a 1 month grace period before the license downgrade occurred; does this mean that now have to wait another month until the license is automatically downgraded to 4SC to get maintenance again for the software updates? I would have though that if there is a "grace period" before the downgrades occurred then software updates should still work. I even tried to "downgrade" myself through my customer portal, however all that it let me to was a free downgrade to 8SC and STILL shows my maintenance expired this morning. EDIT: I am running 15.5SP4 Hope somebody has an idea what will happen, thanks in advance for any assistance.
