10.10.1. Feature Description 
Requirements from the customers for special handling of incoming calls
in OpenScape 4000:
- In the case the incoming number matches a predefined number/pattern, it has to be changed to an internal number - as if the call came from an internal number.
- In the case the incoming number matches a predefined number/pattern,
the incoming party name has to be changed - so the calling party can
be recognized. Alpha tagging: In the case the incoming number matches
a predefined number/pattern, the incoming party name has to be changed
- so the incoming number can be recognized. Call barring: In case the incoming number matches a predefined
number/pattern, one of the following has to be done:
- The call has to be rejected.
- The call has to be routed to a predefined number (hotline destination).
- The call has to be accepted (routed to the original called party).
- The call barring processing described above should also depend on the called destination number (not only on the calling party number).
- No intercept to attendant console if the CLI number is unknown.
