Abstract
Methods and systems are provided that can automatically facilitate busy line validation (BLV) and emergency interrupt (EI) services with the aid of various sensors and systems that can automatically determine the status of a given phone-line, and further provide a menu of services to a calling party. A calling party that encounters a busy signal during an attempt to call a called party can validate the status of the called line without the intervention of a human operator. If the called line is currently used for a voice conversation, as opposed to a modem or facsimile call, then the calling party can optionally interrupt the ongoing conversation with the permission of the called party.
