24 Chapter 2 CallPilot and CS 1000 connectivity overviewPhantom DNsIntroductionInstead of using phonesets or dummy ACD DNs to route calls, CallPilot canuse "virtual telephones" that exist only in software and have no associatedhardware. The DN associated with one of these phantom phones is calleda phantom DN.Creating a Phantom DNTo create a phantom DN, you first create a phantom loop, and then youdefine a TN within that loop. The system recognizes that any TN definedwithin that loop is a phantom TN. Each phantom TN is assigned a DN (thephantom DN). When the DN is entered in the CallPilot Service DirectoryNumber page, it becomes the dialable number of a CallPilot service.Phantom DNs forward to a CDN queueIncoming calls cannot queue up in the phantom TN as they arrive. When acall arrives at a phantom DN, the system forwards it to a CDN queue beforeit is routed to a multimedia channel for further call handling. However, thesystem remembers the phantom DN to keep track of the requested service.Services that should use phantom DNsNortel strongly recommends that you use either phantom DNs or dummyACD DNs (see "Configuring ACD agents" (page 68)) for the followingservices:• all services created with Application Builder that are directly dialableby callers• Speech Activated Messaging• Paced Speech Messaging• Voice Item Maintenance• Fax Item Maintenance• Express Voice Messaging• Express Fax MessagingNetworking servicesThe following Networking services can either have a unique phantom DNconfigured on the CS 1000 system, or they can share the phantom DN(and SDN) of another service:• Enterprise Networking• AMIS Networking• Integrated AMIS NetworkingNortel CallPilotCommunication Server 1000 and CallPilot Server ConfigurationNN44200-312 01.02 Standard5.0 3 May 2007Copyright © 2007, Nortel Networks.
