Abstract

A caller ID based call routing feature. A processing system in the public switched telephone network (PSTN) receives first identifying information for identifying the source of a telephone call and associates additional information stored in a memory with the first identifying information. The additional information may then be transmitted to the subscriber via the Internet for display. Another feature is a branch calling feature where the subscriber may program a processing system within the PSTN to forward an incoming call to two or more end units (e.g., telephones) simultaneously. If the call at an end unit is answered, answer supervision signaling is transmitted back to the processing system which then terminates all other calls. The processing system then connects the calling party to the subscriber. The branch calling may be made for any combination of local, long distance, and cellular telephone numbers.

Claims

1. A method of routing calls from a first network to a second network, comprising:

receiving at a tandem access controller connected to a tandem switch in a PSTN network, an incoming call request relating to a first call from a first user connected to the first network, the first call being directed to a recipient connected to the second network, wherein said receiving takes place without terminating the first call;

generating by the tandem access controller an outbound call request related to a second call, wherein the outbound call request is a function of at least one control criterion available to the tandem access controller;

routing the outbound call request directly to the tandem switch in the PSTN network, without passing through any edge device; and

connecting the first call to the second call when the second call is answered by the recipient connected to the second network.

2. A method according to claim 1, wherein the tandem switch in the PSTN network is not an edge switch and is not directly connected to a user end unit.

3. A method according to claim 2, wherein the first network and the second network operate on disparate communications protocols.

4. A method according to claim 3, wherein the second network is a packet switched network.

5. A method according to claim 2, wherein the control criterion is provided to the tandem access controller through an Internet connection.

6. A method according to claim 2, wherein the control criterion has been previously provided to the tandem access controller by either the first user or the recipient.

7. A method according to claim 2, wherein the control criterion has been previously provided to the tandem access controller by a service provider operating either the first network or the second network.

8. A method according to claim 2, wherein the incoming call request contains at least one of information relating to the first user connected to the first network, or information relating to the recipient connected to the second network.

9. A method according to claim 8, wherein if the information relating to the first user is blocked, the tandem access controller will prompt the first user via a message to provide the blocked information prior to the outbound call request being generated.

10. A method according to claim 4, wherein one or more of the control criteria are modified at the tandem access controller by the recipient through the packet switched network after the outbound call request has been generated.

11. A method according to claim 2, wherein the tandem access controller uses SS7 as a communication protocol.

12. A method according to claim 2, wherein the tandem switch is a PSTN class 4 switch.

13. A method according to claim 4, wherein the packet switched network is a Voice over IP network.

14. A method according to claim 4, wherein the packet switched network is a cellular network.
