If I added the Number of an extention to the line key (for example 200, 300, 400 and 500, see screenshot), will the extention-number
overwritten from the provisioning template every 86400 seconds (by standard setting).
I want, that the extention 200 stays.
What is the interrelation from these 3 files?
Can explain me someone, please, how can I keep the extentions 200-500?
