Abstract
In a method implemented by a telecommunications switch, a call request is made for a called party having a predetermined directory number. A determination is made if preconnection services are to be provided for the called party, and if such services are to be provided, a service node to provide the services is identified. A further determination is made if the call request is from other than the selected service node. If the call request is not from the selected service node, the call request is routed to the service node for preconnection services. If a call request is from the selected service node, the call is routed to the called party. This permits a selected service node to originate a separate call to the called party so that services can be provided on behalf of the called party in response to a call request made by a calling party. This method allows preconnection services to be provided without the requirement of multiple directory numbers being assigned to the called party.
