Abstract

A method may include receiving, at a network device, from a calling party location, an input setup message that includes a called party phone number value; determining whether the input setup message includes a voice telephony over asynchronous transfer mode (VToA) designator; generating an output setup message including an alias address associated with a network gateway that is in communication with a public switched telephone network (PSTN) switch through a plurality of trunk lines when it is determined that the input setup message includes a VToA designator, where the alias address is based on the called party phone number value and indicates a desired trunk line of the plurality of trunk lines; and transmitting the output setup message, the output setup message causing the selection of the desired trunk line of the plurality of trunk lines in order to establish communication between the calling party location and the PSTN switch.

Claims

1. A method, comprising:

receiving, at a network device, from a calling party location, an input setup message that includes a called party phone number value;

determining, at the network device, whether the input setup message includes a voice telephony over asynchronous transfer mode (VToA) designator;

generating, at the network device, an output setup message including an alias address associated with a network gateway that is in communication with a public switched telephone network (PSTN) switch through a plurality of trunk lines when it is determined that the input setup message includes a VToA designator, where the alias address is based on the called party phone number value and indicates a desired trunk line of the plurality of trunk lines; and

transmitting, by the network device, the output setup message, the output setup message causing the selection of the desired trunk line of the plurality of trunk lines in order to establish communication between the calling party location and the PSTN switch.

2. The method of claim 1, where the input setup message includes a calling party phone number value.

3. The method of claim 1, where the input setup message includes an asynchronous transfer mode (ATM) address of a calling party associated with the input setup message.

4. The method of claim 1, where the input setup message includes a called party phone number value stored in a called party subaddress parameter, and the VToA designator stored in a called party number parameter,

5. The method of claim 4, where the input setup message further includes the calling party phone number value stored in a calling party subaddress parameter, and an ATM address of a calling party associated with the input setup message stored in a calling party number parameter.

6. The method of claim 1, where the output setup message includes a called party phone number value stored in a called party subaddress parameter, the alias address stored in a called party number parameter, a calling party phone number value stored in a calling party subaddress parameter, and an ATM address of the calling party associated with the input setup message stored in a calling party number parameter.

7. The method of claim 6, where generating an output setup message including an alias address further comprises identifying the alias address associated with the network gateway using the called party phone number value and indicating a desired trunk line of the plurality of trunk lines in a database of alias addresses based on the calling party phone number value.

8. The method of claim 1, where generating an output setup message including an alias address further comprises locating the alias address in a database of alias addresses based on the called party phone number value.

9. The method of claim 1, further comprising:

determining if the input setup message includes a request for a voice telephony over ATM switched virtual circuit based on the VToA designator.

10. The method of claim 1, where the input setup message is received from an enterprise gateway.

11. The method of claim 1, further comprising:

identifying a modified called party phone number based on the called party phone number value;

generating the alias address based on the modified called party phone number; and

including the modified called party phone number and the alias address in the output setup message.

12. The method of claim 1, where the input setup message is generated by a first telephony device associated with a calling party.

13. The method of claim 1, where the designated trunk line is associated with a second telephony device associated with a called party.

14. An apparatus for providing voice telephony over asynchronous transfer mode (VToA) services and alias addressing using an input asynchronous transfer mode (ATM) switched virtual circuit, comprising:

a multi-service control point to receive an input setup message from a calling party, the input setup message including a called party phone number value,

the multi-service control point to;

determine whether the input setup message includes a VToA designator,

identify a request for VToA services based on the input setup message when the input setup message includes a VToA designator, and

upon identification of such request, generate an output message including an alias address based on the called party phone number value and associated with a network gateway that is in communication with a PSTN switch through a plurality of trunk lines, and where the alias address indicates a desired trunk line of the plurality of trunk lines.

15. The apparatus of claim 14, where the VToA designator is stored in a called party number parameter in the input setup message.

16. The apparatus of claim 14, where the alias address is based on the called party phone number value and a calling party phone number value included in the input setup message.

17. The apparatus of claim 14, where the multi-service control point generates a modified called party phone number value based on the called party phone number value included in the input setup message, and where the alias address is based on the modified called party phone number value.

18. A method, comprising:

intercepting an input asynchronous transfer mode (ATM) setup message from an ingress ATM edge switch of the ATM network;

determining whether the input ATM setup message includes a voice telephony over ATM (VToA) designator;

determining, when the ATM setup message includes a VToA designator, whether the input ATM setup message includes a request for a VToA switched virtual circuit; and

generating, when the input ATM setup message includes a request for a VToA switched virtual circuit, an output ATM setup message including an alias ATM address associated with a network gateway and designating a selected trunk line from among a plurality of trunk lines connecting a PSTN switch to the network gateway, where the selected trunk line is associated with a called party; and

transmitting the output ATM setup message to the ingress ATM edge switch of the ATM network.

19. The method of claim 18, where the VToA designator is stored in a called party number parameter in the input ATM setup message.

20. The method of claim 18, where the alias ATM address is generated based on a called party phone number value and a calling party phone number value in the input ATM setup message.
