Courtesy
A previously activated Courtesy will remain activated if the call is routed to the
alternative destination. Courtesy is not reactivated at the next CDE.
Alternative Destination is Busy
If the original destination is busy, the call is routed to the call distribution element
entered under "CDE if busy". If the alternative destination is also busy, the call is
routed to the next alternative destination -- if such a destination has been config-
ured. This process can be repeated up to the fifth call distribution element. If the
destination of the fifth call distribution element is also busy, the caller will obtain
the busy tone.

Note:
There is little point in using "CDE if busy" together with the destination
combinations "Subscriber and user group, busy" and "Subscriber and
KT line, busy".
