Call connection technique

A method for use in providing a connection between a plurality of users, each of said users employing a simultaneous voice and data (SVD) modem provisioned in a public switched network for interacting with each other over a first connection between said SVD modems, said connection carrying a first one of the two SVD modern channels, the method comprising the step of:

• automatically establishing a second connection between said SVD modems in said public switched network, said second connection carrying the second one of said SVD modern channels, and being independent of the path of said first connection;
• wherein said first connection is via a packet switched network and said second connection is via a circuit switched connection.

A method for use in providing a voice connection between a plurality of users that are each connected to a common data application via respective simultaneous voice and data (SVD) modems, the method comprising the steps of:

• separately routing the data channels supplied from each of said SVD modems of each of said users to a common data application, said routing being independent of the voice channels of said SVD modems;
• and
• connecting the voice channels of ones of said SVD modems in response to a command from said data application.

A method for use in connecting a plurality of users of a common data application, each of said users being connected to said common data application over a connection that passes through a public switched network and includes (i) a first simultaneous voice and data (SVD) modem connected to the user's telephone line for supplying an output having a combined voice and data channel, (ii) a second SVD modem in said public switched network for separating the combined voice and data channel from said first SVD modem into separate voice and data channels, said data channel being connected to said common application, the method comprising the step of:

• connecting together said separate voice channels of each of said plurality of users in said public switched network in response to a command received from said common application, the resulting connection existing independent of said common application, whereby said users can talk to each other over said connected voice channels.

A method for use in connecting a plurality of users of a common data application, each of said users being connected to said common data application over a connection that passes through a public switched network and includes (i) a first simultaneous voice and data (SVD) modem connected to the user's telephone line for supplying an output having a combined voice and data channel, (ii) a second SVD modem in said public switched network for separating the combined voice and data channel from said first SVD modem into separate voice and data channels, said data channel being connected to said common application, the method comprising the step of:

• connecting together said separate voice channels of each of said plurality of users in said public switched network in response to a command received from said common application, the resulting connection existing independent of said common application, whereby said users can talk to each other over said connected voice channels;
• and
• wherein the resulting connection is established via a circuit switched connection.

A method for use in a public switched telephone network having a first simultaneous voice and data (SVD) modem to which a first user has connected a first user SVD modem and a second SVD modem to which a second user has connected a second user SVD modem, a first connection existing between said first and second SVD modems in said public switched network for carrying one of the two SVD modem channels, the method comprising the step of:

• automatically establishing a second connection between said first and second SVD modems of said public switched network, said second connection carrying the other of said two SVD modem channels.

A method for use in providing a connection between a user who is employing a simultaneous voice and data (SVD) modem provisioned in a public switched network for interacting with an application over a first connection between said SVD modem and said application, said connection carrying a first one of the two SVD modem channels, said application having a plurality of different contexts in which said user can interact with said application, said user interaction always being within at least one of said contexts, the method comprising the step of:

• automatically establishing a second connection from said user using the second of said SVD modem channels, said second connection being placed to a particular person via said SVD modem in said public switched network and said particular person being selected as a function of the context in which said user is interacting with said application.

A method for use in providing a connection between a user who is employing a simultaneous voice and data (SVD) modem provisioned in a public switched network for interacting with an application over a first connection between said SVD modem and said application, said connection carrying a first one of the two SVD modem channels, said application having a plurality of different contexts in which said user can interact with said application, said user interaction always being within at least one of said contexts, said SVD modem being associated with an adjunct for controlling and coordinating the routing of said SVD modem channels, the method comprising the steps of:

• determining a destination to which a second connection is to be connected, said determining being responsive to the particular context in which said user is interacting with said application;
• transmitting a message to said adjunct over said first connection instructing said adjunct to establish a connection between said user and said determined destination using the second SVD modem channel.

A method for use in providing a connection between a plurality of users, each of said users employing a simultaneous voice and data (SVD) modem provisioned in a public switched network for interacting with each other over a first connection between said SVD modems, said connection carrying a first one of the two SVD modem channels, the method comprising the step of:

• establishing a second connection between said SVD modems in said public switched network, said second connection carrying the second one of said SVD modem channels and being independent of the path of said first connection;
• said establishing step being characterized in that no destination address is supplied by the one of said users requesting said second connection.

A method for use in providing a connection between a plurality of users, each of said users employing a simultaneous voice and data (SVD) modem provisioned in a public switched network for interacting with each other over a first connection between said SVD modems, said connection carrying a first one of the two SVD modem channels, the method comprising the step of:

• establishing a second connection between said SVD modems in said public switched network, said second connection carrying the second one of said SVD modem channels and being independent of the path of said first connection, said establishing being performed without requiring any dialing by any of said users.

A method for use in providing a connection between a user who is employing a simultaneous voice and data (SVD) modem provisioned in a public switched network for interacting with an application over a first connection between said SVD modem and said application, said connection carrying a first one of the two SVD modem channels, said application having a plurality of different contexts in which said user can interact with said application, said user interaction always being within at least one of said contexts, the method comprising the step of:

• establishing a second connection from said user using the second of said SVD modem channels, said second connection being placed to a particular person via said SVD modem in said public switched network and said particular person being selected as a function of the context in which said user is interacting with said application, said establishing being performed without requiring any destination address to be supplied by said user.
