Abstract

A network is defined with several alternative softswitches/proxies, which may be used for communication. Each softswitch/proxy has a unique Internet Protocol (IP) address. The softswitches/proxies receive configuration data from a centralized user-profile server, which maintains user-profile information. A centralized call-detail record (CDR) server also is connected to each softswitch/proxy and maintains CDRs on each user on each softswitch/proxy. Based on the network configuration, an end-device configuration system generates a provisioning file. The provisioning file includes the IP addresses of each softswitch/proxy. The provisioning file is communicated to user devices. Each user device accesses the provisioning file and uses the IP address for communication. Should the communication fail for any reason, the user device may autonomously access the provisioning file and initiate another call using the next IP address in the provisioning file. This process may continue until a call is completed.

Claims

1. A network comprising:

a user profile server storing user profile information;

a first switch comprising a first internet protocol address in communication with the user profile server and storing first configuration data in response to the user profile information stored in the user profile server;

a second switch comprising a second internet protocol address in communication with the user profile server and storing the first configuration data in response to the user profile information stored in the user profile server; and

a configuration system in communication with the first switch and in communication with the second switch, the configuration system for;

provisioning the network;

generating a provisioning file including the first internet protocol address and the second internet protocol address, wherein the first internet protocol address is different from the second internet protocol address; and

sending the provisioning file to a user device comprising a telephone, wherein the provisioning file instructs the user device to initiate a first call to the first internet protocol address and when the call is not completed, to initiate a second call to the second internet protocol address.

2. The network of claim 1, further comprising,

the user device, wherein the user device is for receiving the provisioning file generated by the configuration system, and wherein the user device is for generating the first call in response to the first internet protocol address and the second call in response to the second internet protocol address included in the provisioning file.

3. The network of claim 1, wherein the first switch and the second switch are softswitches.

4. A method of operating a network, comprising:

storing user profile information;

storing first configuration data in association with a first internet protocol address in response to the user profile information;

storing the first configuration data in association with a second internet protocol address in response to the user profile information;

provisioning the network and generating a provisioning file comprising the first internet protocol address and the second internet protocol address, wherein the first internet protocol address is different from the second internet protocol address; and

sending the provisioning file to a user device, wherein the user device comprises a telephone, wherein the provisioning file instructs the user device to initiate a first call to the first internet protocol address and when the call is not completed, to initiate a second call to the second internet protocol address.

5. The method of claim 4, wherein the first configuration data is stored in a softswitch.

6. A network comprising:

means for storing user profile information;

means for storing first configuration data in association with a first internet protocol address in response to the user profile information;

means for storing the first configuration data in association with a second internet protocol address in response to the user profile information stored in the user profile server;

means for provisioning the network using a provisioning file including the first internet protocol address and the second internet protocol address, wherein the first internet protocol address is different from the second internet protocol address; and

means for sending the provisioning file to a user device, wherein the user device comprises a telephone, wherein the provisioning file instructs the user device to initiate a first call to the first internet protocol address and when the call is not completed, to initiate a second call to the second internet protocol address.

7. The network of claim 6, further comprising,

means for receiving the provisioning file, wherein the receiving means is for generating the first call in response to the first internet protocol address and the second call in response to the second internet protocol address included in the provisioning file.

8. The network of claim 6, wherein the means for storing the first configuration data comprises a softswitch.

9. A user device comprising:

an interface for receiving a provisioning file, the provisioning file comprising a first internet protocol address and a second internet protocol address, wherein the provisioning file instructs the user device to initiate a first call request to the first internet protocol address and when the call request is not completed, to initiate a second call request to the second internet protocol address;

a memory storing the provisioning file including the first internet protocol address and the second internet protocol address; and

a processor coupled to the memory, for generating the first call request to the first internet protocol address and after a predefined time causing the processor to generate the second call request to the second internet protocol address, wherein the first internet protocol address is different from the second internet protocol address, wherein the user device comprises a telephone.

10. The user device of claim 9, wherein the user device is an internet protocol telephone.

11. A method of operating a user device, comprising:

receiving a provisioning file, the provisioning file comprising a first internet protocol address and a second internet protocol address, wherein the provisioning file instructs the user device to initiate a first call to the first internet protocol address and when the call is not completed, to initiate a second call to the second internet protocol address;

storing the provisioning file; and

generating the first call request to the first internet protocol address and after a predefined time generating the second call request to the second internet protocol address in response to the provisioning file, wherein the first internet protocol address is different from the second internet protocol address, wherein the user device comprises a telephone.

12. The method of claim 11, wherein load balancing is initiated in response to the generating the first call request to the first internet protocol address and after the predefined time generating the second call request to the second internet protocol address.
