Abstract

A telecommunications network-based method for alerting a calling party, placed on hold by the called party, that a called party is ready to communicate comprising the steps of receiving an activation signal for activating the network-based system; monitoring the called party's telephone line for availability, where "availability" refers to the situation when the called party removes the hold condition or when the called party is ready to communicate with the calling party, and informing the called party that the Call Hold Stand-by service is alerting the calling party that the called party is available. The network-based method can operate as calling party feature, independent of the called party, or as a feature that is provided by the called party to the calling party.
