Mics Destination


I would like to know, why into Misc Destination, the Dial field appears with a code between {} when i’m selecting a feature code?
In Dial field, it’s wrote “Enter the number this destination will…etc”.

But inside this field, impossible to enter a custom feature code.

If i remember well, into the old freepbx version, i could enter a custom code, right?

Today, the methode about misc destination was changed, or it’s a bug?
