Abstract

A VoIP-UMS accessed via a private branch exchange or an IP-phone using a Session Initiation Protocol (SIP). More particularly, the method has access the VoIP-UMS in which an initial call setup message is sent which includes call information upon accessing the VoIP-UMS for the purpose of using functions, such as voice mail or the like. When a user accesses a voice service system over a network directly from a terminal, the user accesses via an SIP server, or the user accesses via a switching system, the VoIP-UMS can discriminate connected calls easily, and determinate and respond to the calls rapidly because an INVITE message, which is a Session Initiation Protocol message attempting to access the VoIP-UMS, includes an INFO message that is a message on call information.

Claims

1. A method of accessing a voice service system over a network, the method comprising:

upon accessing the voice service system, sending an initial call message, the initial call message including an INFO message that represents call information; and

providing, by the voice service system, a voice service in response to receiving the initial call message including the INFO message.

2. The method according to claim 1, wherein the initial call message is an INVITE message by a Session Initiation Protocol.

3. The method according to claim 1, wherein providing the voice service includes:

providing, by the voice service system, a guide announcement to a user in response to the initial call message; and

accessing, by the user, a voice mailbox according to the guide announcement.

4. The method according to claim 3, wherein the voice mailbox is any one of a user'"'"'s voice mailbox and a called party'"'"'s voice mailbox depending on the INFO message contained in the initial call message.

5. A method of accessing a voice service system where a subscriber connects to a network via a switching system, the method comprising:

connecting to the switching system by the subscriber;

upon accessing the voice service system, sending an initial call message by the switching system, the initial call message containing an INFO message that represents call information; and

providing, by the voice service system, a voice service in response to receiving the initial call message containing the INFO message.

6. The method according to claim 5, wherein providing the voice service includes:

providing, by the voice service system, a guide announcement to a user in response to the initial call message; and

connecting, by the user, to a voice mailbox according to the guide announcement.

7. The method according to claim 6, wherein the voice mailbox is any one of a user'"'"'s voice mailbox and a called party'"'"'s voice mailbox depending on the INFO message contained in the initial call message.

8. A method of accessing a voice service system where a user connects to a network via a terminal, the method comprising:

upon accessing the voice service system via the terminal, sending an initial call message by the user, the initial call message containing an INFO message that represents call information; and

providing, by the voice service system, a voice service in response to receiving the initial call message containing the INFO message.

9. The method according to claim 8, wherein providing the voice service includes:

providing, by the voice service system, a guide announcement to the user in response to the initial call message; and

connecting, by the user, to a voice mailbox according to the guide announcement.

10. The method according to claim 9, wherein the voice mailbox is any one of a user'"'"'s voice mailbox and a called party'"'"'s voice mailbox depending on the INFO message contained in the initial call message.

11. A voice service system for providing a voice service over a network, the system comprising:

a switching system having a Session Initiation Protocol module receiving an initial call message from a subscriber, the initial call message comprising an INFO message that represents call information; and

a voice service device having a Session Initiation Protocol module providing the voice service in response to receiving the initial call message transmitted from the switching system.

12. The system according to claim 11, wherein the initial call message is an INVITE message by a Session Initiation Protocol.

13. The system according to claim 11, wherein the voice service accommodating the voice service system providing a guide announcement to a user in response to the initial call message, and the user connects to the voice mailbox and receives the provided voice service according to the guide announcement.

14. The system according to claim 13, wherein the voice mailbox is any one of a user'"'"'s voice mailbox and a called party'"'"'s voice mailbox depending on the INFO message contained in the initial call message.

15. A voice service system for providing a voice service over a network, the system comprising:

a receiver for receiving an initial call message from a terminal when a subscriber accesses the voice service system, the initial call message containing an INFO message that represents call information; and

a controller having a Session Initiation Protocol module included therein, the Session Initiation Protocol module providing the voice service in response to receiving the initial call message at the receiver.

16. The system according to claim 15, wherein the initial call message is an INVITE message by a Session Initiation Protocol.

17. The system according to claim 15, wherein the voice service is such that the voice service system provides a guide announcement to a user in response to the initial call message, and the user connects to the voice mailbox and receives the provided voice service according to the guide announcement.

18. The system according to claim 17, wherein the voice mailbox is any one of a user'"'"'s voice mailbox and a called party'"'"'s voice mailbox depending on the INFO message contained in the initial call message.

19. A computer-readable medium having computer-executable instructions for performing a method of accessing a voice service system over a network, comprising:

upon accessing the voice service system, sending an initial call message, the initial call message including a first message representing call information; and

providing, by the voice service system, a voice service in response to receiving the initial call message including the first message.

20. A computer-readable medium having stored thereon a data structure comprising:

a first field containing data representing connecting to the switching system by a subscriber;

a second field containing data representing upon accessing the voice service system, sending an initial call message by the switching system, the initial call message including a first message representing call information; and

a third field containing data representing providing, by the voice service system, a voice service in response to receiving the initial call message including the first message.
