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) routing a call from a first local access transport area over the internet to a destination service switching point;

(b) sending an authentication query containing an authentication code to a service control point; and

(c) when a positive authentication response is received, routing the call to a terminating line associated with a dialed long distance number, including a 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 at an originating service switching point.

3. The method of claim 2, further including the step of:

(a2) sending a routing query to the service control point;

(a3) when the call requires routing to an internet telephone carrier, sending a routing response including the authentication code.

4. The method of claim 1, wherein step (a) comprises the step of:

(a1) routing the authentication code to the destination service switching point.

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

(b1) determining a billing information based upon an originating telephone number.

6. 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 transport area;

(b) forwarding the call through an internet carrier to a second local access transport area;

(c) when an indication that a caller identification information is valid is received, routing the long distance call to a terminating line and including the caller identification information.

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

(a1) sending a routing query from a service switching point in the first local access transport area to a service control point;

(a2) receiving a routing instruction from the service control point including an encrypted code.

8. The method of claim 7, wherein step (c) further includes the steps of:

(c1)sending a caller identification query from a service switching point in the second local access 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 transport area.

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

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