Abstract
An apparatus and method for recording/reproducing voice messages using an internet gateway without separately procuring a VMS (Voice Mailing System). Upon receiving the voice message from a subscriber, the voice message is compressed in a data compressor of a digital signal processor (DSP) and stored in a flash memory. Then, the voice message is stored in a buffer of the DSP at a predetermined time interval, and subsequently read and decompressed by a data decompressor, and thereafter reproduced to a calling subscriber.
Claims21
An apparatus for recording/reproducing a voice message in response to an incoming call to an exchange system, said apparatus comprising:
- at least one subscriber unit for entering said voice message;
- and
- an internet gateway arranged within an exchange system for recording/reproducing said voice message, said internet gateway comprising:
- (i) a digital-signal-processor (DSP) having a plurality of ports as data communicating paths, said digital signal processor having buffer, a data compressor for compressing said voice message, and a data decompressor for decompressing said voice message stored in said buffer, and for outputting said voice message via one of said plurality of port;
- (ii) a call processor for establishing a call connection between said subscriber unit and said internet gateway in response to said incoming call and for outputting port information indicating an available port among said plurality of ports;
- (iii) a DSP manager coupled to said call processor for activating said available port of said digital-signal-processor in response to said port information;
- (iv) a flash memory for storing said compressed voice message;
- and,
- (v) a controlling circuit coupled to said flash memory for controlling the stored characteristics of said compressed voice message to be stored in said flash memory and for retrieving said voice message stored in said flash memory in said buffer in response to said incoming call from said telephone unit.
An apparatus for recording a voice message to be announced in response to an incoming call to an exchange system, said apparatus comprising:
- at least one subscriber unit for entering said voice message;
- and
- an internet gateway arranged within an exchange system for recording said voice message, said internet gateway comprising:
- (i) a digital-signal-processor(DSP) having a plurality of ports as data communicating paths, said digital signal processor having a data compressor for compressing said voice message;
- (ii) a call processor for establishing a call connection between said subscriber unit and said internet gateway in response to said incoming call and for outputting port information indicating an available port among said plurality of ports;
- (iii) a DSP manager coupled to said call processor for activating said available port of said digital-signal-processor in response to said port information;
- (iv) a flash memory for storing said compressed voice message;
- and,
- (v) a controlling circuit coupled to said flash memory for controlling the stored characteristics of said compressed voice message to be stored in said flash memory.
An apparatus for reproducing a voice message in response to an incoming call to an exchange system, said apparatus comprising:
- at least one subscriber unit;
- and
- an internet gateway arranged within an exchange system for playing said voice message stored therein in response to said incoming call, said internet gateway comprising:
- (i) a flash memory for storing said voice message having at least one message;
- (ii) a digital-signal-processor having a plurality of ports, a buffer and a data decompressor for decompressing said voice message stored in said buffer, and for outputting said decompressed voice message via one of said plurality of port;
- (iii) a controlling circuit coupled to said flash memory for retrieving said voice message stored in said flash memory in said buffer and for storing said retrieved voice message in said buffer in response to said incoming call from said telephone unit;
- (iv) a call processor for establishing a call connection between said subscriber unit and said internet gateway in response to said incoming call from said telephone unit, for outputting port information indicating an available port among said plurality of ports of said digital-signal-processor, and for outputting said voice message responsive to said incoming call;
- and,
- (v) a DSP manager coupled to said call processor for activating said available port of said digital-signal-processor in response to said port information.
