None DID
When selected None DID, all incoming calls will enter IVR system
instead of directly dial to a specified extension. Select a
preferred IVR from IVR list for this trunk.
Extension DID
When selected Extension DID, select an extension in the list to

If prefix or stripping has been given, the result of digit

If you set a DID extension in a trunk, then only that extension
can use this trunk to call out, and all incoming calls to this
trunk will connect to that extension directly.
DID By Number

corresponding extension derived by number manipulation. The
