The internal number of a call distribution element can only be used as the
destination for a CFU in a special case, namely if at least one CDE destina-
tion is configured on ACD. If not, Not available is displayed whenever the
function is activated. Any configured CDE destinations that are not ACD
are never executed.

• Internal: CFU chains can be set up locally (maximum 20);
• In the PISN: CFU chains are permitted. They are however restricted by the transit
counter.
