I'm curious if anyone else has seen this. All of the workstations are Windows 7 Pro. The 3CX Windows Phone is losing it's config after logoff or reboot on 5 of the 67 computers. I've tried a different user profile (me) on a couple issues and it seems to happen on those same computers regardless of which using logs in. If I reprovision from the config file it works fine... Until the next reboot. All the computers are at the same patch level. The c:\program data\3cx phone for windows directory is exempted for the AV software (Vipre). Any one have any suggestions?
