Changing extensions length 3CX

Today I'll show you how to change the digit length of your extensions in 3CX once installed.
Please note that this is not recommended and should be tested and of course take a backup of your database first!.

To change the extension length go to "settings" --> Advanced --> choose the "custom parameter tab" and look for the value called :  "ENL" , change the value field to the desired length and you're done!
