## Abstract

A system subsidizes telephone calls over a network. The system includes a service provider 120 that establishes a telephone call between a calling party terminal 130 and a called party terminal 140 over the network 110. During the telephone call, the service provider causes at least one advertisement 312 to be displayed at the calling, or called party terminal. At any time during, or after, the telephone call, the service provider generates a bill based on a subsidized billing rate related to the display of the at least one advertisement.

## Claims

### Claim 1

A method for subsidizing telephone calls over a digital network carrying VoIP traffic, said network including at least one client computer terminal and a VoIP service provider, said method comprising:
establishing a telephone call between the client computer terminal and a receiving terminal over the digital network;
causing the client computer terminal to display at least one advertisement during the telephone call;
determining whether the receiving terminal accepts advertisements;
causing the receiving terminal to display at least one other advertisement when the receiving terminal accepts advertisements;
determining a subsidized billing rate based on the display of the at least one advertisement at the client computer terminal and the display of the at least one other advertisement at the receiving terminal; and
generating a bill for the telephone call based on the subsidized billing rate.

### Claim 2 (depends on 1)

The method of claim 1 wherein the receiving terminal is a client computer terminal.

### Claim 3 (depends on 1)

The method of claim 1 wherein an amount of subsidization is based on personal traits of a user of the client computer terminal.

### Claim 4 (depends on 1)

The method of claim 1 wherein an amount of subsidization is based on advertising revenue derived from display of the at least one advertisement.

### Claim 5 (depends on 1)

The method of claim 1 wherein said bill is generated for any period of time after inception of a client's account.

### Claim 6 (depends on 1)

The method of claim 1 wherein a content of the at least one advertisement is based on a geographical location of the clients computer terminal and a telephone number of the client computer terminal.

### Claim 7 (depends on 1)

The method of claim 1 wherein the displaying of the at least one advertisement occurs prior to and during the telephone call.

### Claim 8 (depends on 1)

The method of claim 1 further comprising:
increasing a balance of an account associated with the client computer terminal by banking minutes prior to the current telephone call.

### Claim 9 (depends on 8)

The method of claim 8 wherein the banked minutes are increased when advertising is accepted by the client computer terminal.

### Claim 10 (depends on 8)

### Claim 13 (depends on 12)

The method of claim 12 wherein the receiving terminal authorizes said collect call.

### Claim 14

A system for subsidizing telephone calls over a VoIP network including at least one client computer terminal and a VoIP service provider, said system comprising:
means for establishing a telephone call between the client computer terminal and a receiving terminal over the VoIP network;
means for causing the client computer terminal to display at least one advertisement during the telephone call;
means for determining a subsidized billing rate based on the display of the at least one advertisement;
means for determining whether the receiving terminal accepts advertisements;
means for reducing the subsidized billing rate when the receiving terminal accepts advertisements; and
means for generating a bill for the telephone call based on the reduced subsidized billing rate.
