Endpoint updates began over writing aastra.cfg again

Latest endpoint updates have started over writing my aastra.cfg again, it did not do this since the first time I updated to 12.

I don’t use this module and prefer to create my own custom config files for my aastra phones. When I originally installed the system years ago I uninstalled the OSS version as it presented its own problems for me but a lot has changed over the years and all commercial modules are installed whether we like it or not and discussions sound as though that is not going to change as it provides an advertising venue.

What is the easy solution as it is endpoint is interdependent on other commercial modules that I might want to use in the future.
Just continue to login and overwrite with my backup each time?

Just disable EPM module and when you update modules it wont update that one anymore.
