I have a few customers using 3CXPhone for windows and they are constantly having the application lose the config. What we see happening is that a user can open the attachment from their email and it loads it up just fine but as soon as the user logs off the computer and back in the 3CX application no longer has there config and is requiring them to re-open the attachment again. We are seeing this at more then one location all running the current V12 SP1. One location is using it on a 2008R2 Terminal server with a number of users all having the same thing happen when they logoff and back on the config is reset. In another location it is just a windows 7 computer and every time the user logs off and back on it is gone.... Has anyone else saw this behavior? Any ideas on the cause?
