Abstract:
A Voice Messaging System (VMS) offers a voice store and forward service to a caller on an incomplete call. The caller records the voice message at a Message Delivery System (MDS) via an Intercept Processing Unit (IPU) during a recording session. Call related parameters are transferred from the IPU to the MDS utilizing a handshake protocol specific to the IPU. The VMS accommodates different types of IPUs having different call parameter transfer protocols. The system displays, on the administration terminal, protocol maintenance screens including a generic list of call parameters with fields for entering the order and field length of selected parameters so as to designate a protocol specification to the system. The fields also include information regarding the delimiters utilized to separate the parameters of a parameter string and to designate the end of a parameter string. The protocol specifications are stored in protocol tables keyed by CALLTYPE designating the type of IPU calling the MDS.

Abstract:
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.
