Hello everyone we have Fusion PBX, Ver 4.5.30 and using provisioning for Grand Stream phone GRP 2613 on remote locations, if there is an network outage (or we unplug phone for few minutes) at site and doesn't restore before registration expire (I am using 120 sec for registration expiry) phones never register back unless we factory reset phones and re-setup either manually or use provisioning services form fusion, any one have similar issues or know the work around this please
