ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a combined voicemail/EMail and private branch exchange (PBX) system and method for providing voice response to an EMail message.
BACKGROUND OF THE INVENTION
Hand-held computing devices with integrated telephones have been available for some time. The purpose of these devices is to allow mobile users to perform simple operations, such as sending or receiving EMail, and accessing information services, without carrying a bulky laptop computer. Unfortunately, even though these devices are significantly smaller than the equivalent laptop computer/cellular phone combination, they are too bulky to suit the demands of most users, and have therefore been poorly received in the market. The bulk of these early devices is the perceived requirement of a QWERTY keypad and large, by cellular phone standards, display, usually in the form of a LCD. The developers of these first generation devices believe that these components are necessary in order to support the primary data application: sending and receiving EMail.
In order to appeal to the broader market, it is necessary that these devices support voice and EMail, and that they be equivalent in size and cost to traditional cellular phones. This is not as difficult as it may seem. First, voice operation is a given. Second, one may argue that EMail sent to mobile users is different than that which is sent to fixed-base users in that the length is generally constrained to several sentences, and attachments are not included. This difference in message composition exists because present-day wireless devices, such as alphanumeric pagers, typically are not capable of processing attachments, the relatively small display size limits the amount of text that is displayed at one time, and the scrolling capability is limited by user patience.
Alphanumeric paging and digital cellular (DC)/personal communications system (PCS) operators offer infrastructure-based services which allow conventional EMail, up to several hundred characters in length to be routed to wireless users. The 3-4 line screens, present on many high-end DC and PCS voice phones are large enough to allow perusal of short text messages. The reception of an EMail message by a user of a DC/PCS device may be supported on a conventional voice phone platform, already in place.
The problem arises when a user wishes to reply to a message. Dedicated QWERTY keyboards consume excessive space, handwriting recognition is cumbersome, and requires the use of a stylus which is likely to be misplaced, and reliable voice recognition requires resources which cannot be deployed, given the previously-mentioned size and cost constraints.
Key industry players have indicated that future voicemail/EMail products will support a reply mechanism which allows the recipient to view the text-based EMail and then compose a voice memo in reply. The voice memo is captured by the device and stored as a compressed audio file which is then mailed to the message originator. While this may be one solution to the problem, it may not be a viable business solution to those millions of business users throughout the world who continue to us legacy PCs, i.e., x486-based and older equipment, that will not adequately support audio file presentation. For this scheme to work, the recipient must have access to a multimedia-capable PC in order to playback the reply. Furthermore, most cubicle-resident business users would prefer not to have sensitive EMail “broadcast” to co-workers who happen to be listening nearby. Neither is the problem solved in the case where a user polls EMail with a DC/PCS device having limited display, and no capability to play a voice file.
The majority of the voice-related EMail prior art is in the field of voice transmission over the internet, using internet protocol (IP). The prior art disclosed various gateways which offer the inverse to the invention described herein, namely, the conversion of voice-to-data in preparation for real-time transmission across an IP network.

SUMMARY OF THE INVENTION
A system for providing a voice response to an EMail message, wherein the voice response is generated by a thin client device and transmitted to a cellular, or similar, service and then to a world-wide communications network, includes a conversion mechanism co-located with the cellular service for converting the voice response into a voice data file which is transmitted over the world-wide communications network; an EMail server connected to the world-wide communications network for receiving conventional EMail and voice data files; an EMail-to-voicemail gateway for identifying voice data files; a voicemail interface for receiving voice data files from said EMail-to-voicemail gateway and converting said voice data files into voice streams; a voicemail system, including recipient voicemail boxes; for directing said voice streams into a recipient's voicemail box.
A method of generating a voicemail message with a thin client device and transmitting that voicemail message over an EMail system, includes sending a voice mail message over a wireless phone system; converting the voice mail message into a voice data file; transmitting a the voice data file over a world-wide communications network; receiving the voice data file at an EMail server; separating the voice data file from EMail files; changing the voice data file into a voice stream; and directing the voice stream to a recipient's voicemail box.
An object of the invention is to provide a mechanism by which aud
