Prompt issuing protocol for an intercept voice messaging system

摘要

A voice messaging service system for caller accepted voice store and forward service. The service offering prompt is issued during dial tone in response to caller off-hook, advising that the service can be accepted by the caller if the call to the intended recipient is not completed. Alternatively, the service offering prompt is delayed after caller off-hook for a time interval sufficient for the caller to dial the telephone number of the intended recipient. As a further embodiment, the service is offered for acceptance by the caller without advancing the call to the intended recipient.
