We've got several SX20's, all standalone, not registering to CUCM or any Gatekeeper. We've got H.323 enabled and set as the default protocol. We're on a few different versions of software, ranging from 9.1.4 to 9.7.x. We see it every once in awhile where calls stop working. We look at the codec and there's a message that H.323 is the default protocol but is not configured. In this case, we find the H.323 section has completely disappeared from the device. I don't have a screenshot of it, but it's gone from the list on the left. We do an upgrade or downgrade and with the reboot, H.323 comes back. I have not been able to find anything out there that seems to have this same issue. We've seen it on at least 3 different SX20s. Anyone seen this issue before?
