Abstract

A system and method is provided for routing telephone calls on a standard telephone network to one of a PSTN network and a VoIP network. The system comprises at least one telephone capable of making local and long distance calls on the network. A Central Office is coupled to the telephone and comprises a trigger for identifying calls to be routed to either a VoIP platform or the PSTN network. Calls to be converted to IP protocol are routed to a VoIP platform. An IP network is coupled to the VoIP platform and routes VoIP calls to one or more devices in communication with the telecommunications system.

Claims

1. A telecommunications system for routing telephone calls comprising:

a trigger configured to identify automatically an initiated telephone call for packetized or non-packetized routing wherein the trigger is part of a feature phone and identified by the feature phone and not identified by the router; and

further comprising at least one of the following;

wherein the initiated telephone call is identified based on “

1+”

dialing,

wherein the initiated telephone call is identified based on “

ANI;

”

wherein the initiated telephone call is identified based on an area code;

wherein the initiated telephone call is identified based on primary interexchange carrier (PIC);

wherein the initiated telephone call is received from a cellular telephone;

wherein the initiated telephone call is received from a telephone device having a plurality of standard telephone lines on the standard telephone network and initiated telephone calls from the plurality of telephone lines are identified based on associated predefined account codes; and

wherein the system further comprises a telephone device coupled to the router, that generates the incoming telephone call and wherein the telephone device comprises a feature phone that includes identification means for identifying calls to be routed over the packetized protocol network and the feature phone is not an Internet phone.

2. The system of claim 1, wherein the initiated telephone call is identified based on “

1+”

dialing.

3. The system of claim 1, wherein the initiated telephone call is identified based on “

ANI.”

4. The system of claim 1, wherein the initiated telephone call is identified based on an area code.

5. The system of claim 1, wherein the initiated telephone call is identified based on PIC.

6. The system of claim 1, wherein the initiated telephone call is received from a cellular telephone.

7. The system of claim 1, wherein the initiated telephone call is received from a telephone device having a plurality of standard telephone lines on the standard telephone network and wherein initiated telephone calls from the plurality of telephone lines are identified based on associated predefined account codes.

8. The system of claim 1, further comprising a telephone device coupled to the router, that generates the incoming telephone call and wherein the telephone device comprises a feature phone that includes identification means for identifying calls to be routed over the packetized protocol network.

9. A telecommunications system for selectively routing telephone calls using a Voice over Internet Protocol (VoIP) network or a circuit switched telephone network comprising:

a trigger configured to identify automatically an initiated telephone call for packetized or non-packetized routing wherein the trigger is part of a feature phone and identified by the feature phone and not identified by the router; and

a Voice Over Internet Protocol platform coupled to the router and configured to receive the telephone call from the router when the call is routed over the VoIP network and to convert the telephone call to VoIP for routing over the VoIP network;

further comprising at least one of the following;

wherein the initiated telephone call is identified based on “

1+”

dialing;

wherein the initiated telephone call is identified based on “

ANI;

”

wherein the initiated telephone call is identified based on an area code;

wherein the initiated telephone call is received from a cellular telephone;

wherein the initiated telephone call is received from a telephone device having a plurality of standard telephone lines on the standard telephone network and initiated telephone calls from the plurality of telephone lines are identified based on associated predefined account codes; and

wherein the system further comprises a telephone device coupled to the router, that generates the initiated telephone call and wherein the telephone device comprises a feature phone that includes identification means for identifying calls to be routed over the packetized protocol network and the feature phone is not an Internet phone.

10. The system of claim 9, wherein the initiated telephone call is identified based on “

1+”

dialing.

11. The system of claim 9, wherein the initiated telephone call is identified based on “

ANI.”

12. The system of claim 9, wherein the initiated telephone call is identified based on an area code.

13. The system of claim 9, wherein the initiated telephone call is received from a cellular telephone.

14. The system of claim 9, wherein the initiated telephone call is received from a telephone device having a plurality of standard telephone lines on the standard telephone network, wherein the initiated telephone call from the plurality of telephone lines is identified based on an associated predefined account code.

15. The system of claim 9, further comprising a telephone device coupled to the router, that generates the initiated telephone call and wherein the telephone device comprises a feature phone that includes identification means for identifying calls to be routed over the packetized protocol network.
