Abstract

A call rerouter routes a call through a data link when a called party is engaged in a data call. The call rerouter evokes a 'T' connection in a switch that is in a connection path of the called party's call and determines whether the called party is engaged in a data call or a non-data call. If engaged in a data call, the rerouter retrieves called party information to determine if the called party is a subscriber to a data network such as an Internet Service Provider (ISP). If so, the call rerouter informs the called party through the data network that a call is waiting to be connected. If the called party desires, the rerouter routes the call through the data network to be connected with the called party. If the called party is not a subscriber to an ISP (or data network) or not engaged in a data call, the call rerouter returns a message to the calling party that the called party is unavailable.
