Provisioning unified messaging system services

1. A method, comprising:

providing a messaging service using a messaging system, wherein the messaging system includes:

a centralized Internet Protocol switching network;

an Internet access subsystem coupled to the centralized Internet Protocol switching network via a first communication link, the first communication link integrated with and internal to the messaging system;

a voice access subsystem coupled to the centralized Internet Protocol switching network via a second communication link, the second communication link comprising a second internal link within the messaging system;

a mail subsystem coupled to the Internet Protocol switching network via a third communication link integrated with and internal to the messaging system; and

a storage subsystem coupled to the centralized Internet Protocol Switching network via a fourth communication link, wherein the fourth communication link is integrated with and internal to the messaging system.

2. The method of claim 1 , further comprising receiving a request to provide the messaging service to a subscriber.

3. The method of claim 2 , wherein the messaging service is provided to the subscriber.

4. The method of claim 3 , wherein the messaging service includes providing the subscriber access to stored voice mail and electronic mail messages.

5. The method of claim 4 , wherein the messaging service is operated by a messaging entity.

6. The method of claim 5 , further comprising sending a billing statement to the subscriber, wherein the billing statement including charges related to the messaging service provided by the messaging entity.

7. The method of claim 1 wherein the first communication link is configured to transfer data according to a Hyper-Text Transfer Protocol.

8. The method of claim 1 , wherein the second communication link is configured to transfer data according to a Voice over Internet Protocol format.

9. The method of claim 1 , wherein the third communication link is configured to transfer data according to at least one of a Simple Mail Transfer Protocol, a Post Office Protocol, and an Internet Message Access Protocol.

10. A method, comprising:

receiving a request for a messaging service at an order center, the order center placing a service order with a telephone entity element and with a messaging entity element, wherein the messaging service comprises providing access to a messaging system that includes:

a centralized Internet Protocol switching network;

an Internet access subsystem coupled to the centralized Internet Protocol switching network via a first communication link, the first communication link integrated with and internal to the messaging system;

a voice access subsystem coupled to the centralized Internet Protocol switching network via a second communication link, the second communication link comprising a second internal link within the messaging system;

a mail subsystem coupled to the Internet Protocol switching network via a third communication link integrated with and internal to the messaging system; and

a storage subsystem coupled to the centralized Internet Protocol switching network via a fourth communication link, wherein the fourth communication link is integrated with and internal to the messaging system.

11. The method of claim 10 , wherein the request for the messaging service is received from a subscriber.

12. The method of claim 11 , further comprising sending a billing statement from the telephone entity, the billing statement including charges related to the messaging service.

13. The method of claim 12 , further comprising providing the messaging service to the subscriber, wherein the messaging service is operated by the messaging entity.

14. The method of claim 10 , wherein the first communication link is configured to transfer data according to a Hyper-Text Transfer Protocol.

15. A method of handling data messages in connection with providing a unified messaging system service, the method comprising:

receiving a data message by the unified messaging system at an Internet access subsystem, the Internet access subsystem coupled to a centralized Internet Protocol switching network via a first communication link, wherein the centralized Internet Protocol switching network is integrated with, and internal to the unified messaging system;

receiving a voice message by the unified messaging system at a voice access subsystem coupled to the centralized Internet Protocol switching network via a second communication link;

storing at least one of the data message and the voice message at a storage subsystem coupled to the centralized Internet Protocol switching network via a third communication link, wherein the third communication link is integrated with and internal to the unified messaging system; and

sending at least one of the data message and the voice message using a mail subsystem coupled to the centralized Internet Protocol switching network.

16. The method of claim 15 , wherein the second communication link is integrated with and internal to the unified messaging system.

17. The method of claim 15 , wherein the mail subsystem is coupled to the centralized Internet Protocol switching network via a fourth communication link.

18. The method of claim 17 , wherein the fourth communication link is integrated with and internal to the unified messaging system.

19. The method of claim 15 , wherein the data message is sent by attaching the data message in a mail message transmitted using the mail subsystem.

20. The method of claim 15 , wherein the voice message is sent by attaching the voice message in a mail message transmitted using the mail subsystem.
