For some reason my PBX very often fails to register/activate with Freepbx, which means none of my commercial modules work.
I once changed the NIC in this server but that is all. I have just tried updating to system admin beta .38 but that also seems to make no difference. This has been going on for a long while but normally sorts itself out within 1 or 2 reboots. Right now 5 reboots and no activation.
