System and method for using alternative switch announcements in advanced intelligent network services

摘要

In a public switched telephone network, a method and system are provided for utilization of regular non-intelligent switch announcements for announcement provision for intelligent network services calls. A call received in the network and directed to a particular number has its identification information read and compared to entries in a database. If the call requires announcement treatment, a unique carrier identification code is assigned to the call identification information which causes the intelligent facilities of the network to route the call to a regular non-intelligent switch announcement frame resident in the non-intelligent network facilities at a central office switch. The regular non-intelligent switch announcement frame provides an announcement to the calling party.
