I have noticed, that when I change the display name of an extension in FreePBX, the change doesn't get updated in FOP2 Manager. I have to do that manually there.
Any way you could add this function to a future release?
I might add an option for doing sync labels automatically in a future release. Right now I am adding the mass csv update in the manager buttons page you suggested in another thread. Its working already, but I have to add error checking, alert messages and translations.
