  • Method and system for playing packetized announcements to telephone network end office switching systems from a centralized digital recorded announcement unit
    Patent number: 7406158
    Abstract: A centralized recorded announcement unit shared by multiple end offices on a public switched telephone network stores announcements in digital files. When a call is received at a switch and an announcement is required, the announcement is played to the caller by an announcement device if the particular announcement file is stored locally. If the announcement is not stored locally, a request is sent to the centralized recorded announcement unit to retrieve the announcement file and play the announcement to the caller. Both the request and the announcement file are sent via a packed-switched network.
