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

1. A method of providing caller identification for calls placed over an internet, comprising the steps of:

(a) receiving a dialed long distance number at an originating service switching point;

(b) sending a routing query to a service control point;

(c) when the call requires routing to an internet telephone carrier, sending a routing response including an authentication code;

(d) routing the call including a caller identification field to an originating point of presence for the internet telephone carrier;

(e) routing the call over the internet to a destination point of presence for the internet telephone carrier;

(f) routing the call to a destination service switching point;

(g) determining a billing information based upon an originating telephone number;

(h) sending an authentication query containing the authentication code to the service control point; and

(i) 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.

2. The method of claim 1, wherein step (a) further includes the step of:

(a1) triggering on the dialed long distance number.

3. The method of claim 1, wherein the routing query of step (b) comprises the dialed long distance number and an originating telephone number.

4. The method of claim 1, wherein the routing, response of step (c) includes an authentication code.

5. The method of claim 4, wherein step (h) further includes the step of:

performing a validation of the authentication code.

6. A method of providing caller identification for calls placed over an internet, comprising the steps of:

(a) receiving a call request at a service switching point;

(b) sending a routing query to a service control point;

(c) receiving a routing instruction to an originating point of presence for an internet carrier;

(d) routing the call over the internet carrier;

(e) determining a billing information based upon an originating telephone number;

(f) sending a caller identification query to the service control point;

(g) receiving a caller identification response from the service control point; and

(h) routing the call to a terminating line associated with a dialed long distance number and including a caller identification information.

7. The method of claim 6, wherein step (a) further includes the step of:

(a1) triggering on a dialed long distance number.

8. A method of providing caller identification for calls placed over an internet comprising the steps of:

(a) originating a long distance call in a first local access and transport area;

(b) forwarding the call to an internet carrier;

(c) forwarding the call to a second local access and transport area;

(d) receiving an indication that a caller identification information is valid;

(e) routing the long distance call to a terminating line and including the caller identification information.

9. The method of claim 8, wherein step (b) further includes the steps of:

(b1) sending a routing query from a service switching point in the first local access transport area to a service control point;

(b2) receiving a routing instruction from the service control point including an encrypted code.

10. The method of claim 9, wherein step (c) further includes the steps of:

(c1) sending a caller identification query from a service switching point in the second local access and transport area to the service control point, including the encrypted code;

(c2) determining that the encrypted code is valid;

(c3) sending a valid indication to the service switching point in the second local access and transport area.

11. The method of claim 10, wherein step (c) further includes the steps of:

(c4) determining that the encrypted code is not valid.
