Abstract

The present invention provides audio messaging in a communications network, e.g., a VoIP network. More specifically, the present invention establishes a non-duplex communication link between a first subscriber and a second subscriber. Audio messages are transmitted between the first subscriber and the second subscriber via the non-duplex communication link.

Claims

1. A method for providing audio messaging, comprising:

establishing a non-duplex communication link between a first subscriber and a second subscriber, wherein said non-duplex communication link is an open line between said first subscriber and said second subscriber; and

transmitting recorded audio messages between the first subscriber and the second subscriber via the non-duplex communication link, wherein an automatic attempt is made to re-establish the non-duplex communication link when one party becomes disconnected.

2. A method for providing audio messaging, comprising:

establishing a non-duplex communication link between a first subscriber and a second subscriber, wherein said non-duplex communication link is an open line between said first subscriber and said second subscriber; and

transmitting recorded audio messages between the first subscriber and the second subscriber via the non-duplex communication link, wherein, in response to an input from one of said first subscriber or said second subscriber, the non-duplex communication link is temporarily suspended while the one of said first subscriber or said second subscriber initiates another call.

3. An apparatus for providing audio messaging, comprising:

means for establishing a non-duplex communication link between a first subscriber and a second subscriber, wherein said non-duplex communication link is an open line between said first subscriber and said second subscriber; and

means for transmitting recorded audio messages between the first subscriber and the second subscriber via the non-duplex communication link, wherein, in response to an input from one of said first subscriber or said second subscriber, the non-duplex communication link is temporarily suspended while the one of said first subscriber or said second subscriber initiates another call.

4. A computer-readable medium having stored thereon a plurality of instructions, the plurality of instructions including instructions which, when executed by a processor, cause the processor to perform the steps of a method for providing audio messaging, comprising:

establishing a non-duplex communication link between a first subscriber and a second subscriber, wherein said non-duplex communication link is an open line between said first subscriber and said second subscriber; and

transmitting recorded audio messages between the first subscriber and the second subscriber via the non-duplex communication link, wherein an automatic attempt is made to re-establish the non-duplex communication link when one party becomes disconnected.

5. A computer-readable medium having stored thereon a plurality of instructions, the plurality of instructions including instructions which, when executed by a processor, cause the processor to perform the steps of a method for providing audio messaging, comprising:

establishing a non-duplex communication link between a first subscriber and a second subscriber, wherein said non-duplex communication link is an open line between said first subscriber and said second subscriber; and

transmitting recorded audio messages between the first subscriber and the second subscriber via the non-duplex communication link, wherein, in response to an input from one of said first subscriber or said second subscriber, the non-duplex communication link is temporarily suspended while the one of said first subscriber or said second subscriber initiates another call.
