Abstract: The present invention provides a subscriber with a single interface to access one or more Voice-Based Communications Systems (hereinafter “VCSs”). By employing automatic speech recognition and/or natural language understanding (hereinafter “ASR/NLU”) technologies and capabilities, the system can interact with a VCS account without direct human interaction. The system logs into a VCS account by generating voice commands (e.g., using text to speech technology or recorded voice commands) and/or DTMF, and then precedes to conduct an automated voice-based dialogue with the VCS in order to obtain notification, voice communications and/or other information. Since the system employs ASR/NLU technologies and capabilities, it can record any notifications and communications from the VCS, optionally convert them into other data signals (e.g., digital data) and then transmit them over and/or store them on other mediums.

Abstract: Disclosed is a telephony messaging transfer system permitting a messaging host to redistribute its processing and/or storage load to another messaging host. An administrator can dynamically control the amount of time needed to transfer specified mailboxes by monitoring the progress on-line and increasing or decreasing the number of transfer dialogs to be used in the transfer process. Also provided is a predictive simulator for simulating the transfer process and providing statistics that can be used to adjust the timing of the actual transfer.
