## Abstract

The invention uses the advanced intelligent network to provide caller identification for calls placed over the internet (24). A long distance call placed with an internet carrier results in the originating SSP (14) forwarding the call to an originating POP (22) for the internet carrier. The caller ID information is routed through the signaling system 7 network (16) to the SSP (32) in the terminating network. The call is routed to a terminating POP (26) and then to the SSP (32) in the terminating network. The SSP (32) inserts the caller ID information received through the SS7 network (16) and routes the call to the terminating line (30).

## Claims

### Claim 1

(a) receiving a dialed long distance number at an originating service switching point;
(b) triggering on the dialed long distance number;
(c) sending a routing query, containing the dialed long distance number and an originating telephone line, to a service control point;
(d) when the call requires routing to an internet telephone carrier, sending a routing response including an authentication code;
(e) routing the call including a caller identification field to an originating point of presence for the internet telephone carrier;
(f) routing the call over the internet to a destination point of presence for the internet telephone carrier;
(g) routing the call to a destination service switching point;
(h) the call encounters a trigger;
(i) sending an authentication query containing the authentication code to the service control point;
(k) performing a validation of the authentication code; and
(l) when a positive authentication response is received, routing the call to a terminating line associated with the dialed long distance number, including the caller identification field.

### Claim 2 (depends on 1)

The method of claim 1, further including the steps of:
(m) when the positive authentication response is not received, routing the call to the terminating line associated with the dialed long distance number with an indicator that a caller identification information is unreliable.

### Claim 3 (depends on 1)

The method of claim 1, further including the steps of:
(m) when the positive authentication response is not received routing the call to the termination line associated with the dialed long distance number without the caller identification field.

### Claim 4

A method of providing caller identification for calls placed over an internet, comprising the steps of:
(a) receiving a call request including a dialed long distance number at a service switching point;
(b) triggering on the long distance number;
(c) sending a routing query to a service control point;
(d) receiving a routing instruction to an originating point of presence for an internet carrier;
(e) routing the call to the originating point of presence for the internet carrier;
(f) routing the call to a destination point of presence for the internet carrier;
(g) routing the call to a destination service switching point;
(h) sending a caller identification query to the service control point;
(i) receiving a caller identification response from the service control point; and
(j) routing the call to a terminating line associated with the dialed long distance number and including a caller identification information.

### Claim 5 (depends on 4)

The method of claim 4, wherein step (c) further includes the step of:
(c1) sending the dialed long distance number and an originating telephone line as part of the routing query.

### Claim 6 (depends on 4)

The method of claim 4, wherein step (d) further includes the steps of:
(d1) determining if the call is to be routed to the internet carrier;
(d2) when the call is to be routed to the internet carrier, calculating an authentication code;
(d3) sending the authentication code as part of the routing instruction.

### Claim 7 (depends on 6)

The method of claim 6, wherein step (e) further includes the step of:
(e1) sending the authentication code to the originating point of presence.

### Claim 8 (depends on 6)

The method of claim 6, wherein step (f) further includes the step of:
(f1) sending the authentication code to the destination point of presence.

### Claim 9 (depends on 6)

The method of claim 6, wherein step (g) further includes the step of:
(g1) sending the authentication code to the destination service switching point.

### Claim 10 (depends on 6)

The method of claim 6, wherein step (h) further includes the step of:
(h1) sending the authentication code to the service control point as part of the caller identification query.

### Claim 11 (depends on 6)

The method of claim 6, wherein step (i) further includes the steps of:
(i1) determining if the authentication code is valid;
(i2) when the authentication code is not valid, routing the call to the terminating line without the caller identification information;
(i3) when the authentication code is valid, proceeding to step (j).

### Claim 12 (depends on 4)

The method of claim 4, wherein step (d) further includes the steps of:
(d1) determining if the call is to be routed to the internet carrier;
(d2) when the call is to be routed to the internet carrier, storing a call processing record including an originating telephone line and the dialed long distance number.

### Claim 13 (depends on 12)

The method of claim 12, step (i) further includes the steps of:
(i1) determining if the caller identification query is associated with the call processing record;
(i2) when the caller identification query is associated with the call processing record, sending a caller identification valid as part of the caller identification response;
(i3) when the caller identification query is not associated with the call processing record, routing the call to the terminating line without the caller identification information.

### Claim 14 (depends on 13)
