A system in which centralized announcement platforms are connected to host switches over dedicated trunks, and remote switches needing announcement services send a signaling message to a host switch requesting a connection to the announcement platform. A connection is then established between the host switch and the remote switch over a regular trunk, and the full connection is completed over a dedicated circuit between the host switch and the announcement platform. Announcement message ID and other information required by the announcement platform is coded in the available parameter fields of a signaling message. Less total circuits are required and redundancy is provided.
