Abstract

Systems, methods, apparatus and computer program products are provided for sharing a resource including a subscription engine configured to subscribe to a first turret system to share the resource, a state change engine configured to receive a state change notification corresponding to the resource, from the turret system, and a failover engine configured to invite the turret system to initiate a connection to the resource.

Claims

1. An apparatus for sharing a resource, comprising:

a subscription engine configured to subscribe to a first turret system to share the resource;

a state change engine configured to receive a state change notification corresponding to the resource, from the turret system; and

a failover engine configured to invite the turret system to initiate a connection to the resource.

2. The apparatus of claim 1, wherein the subscription engine, the state change engine and the failover engine are Session Initiation Protocol (SIP) user agents.

3. The apparatus of claim 2, wherein the SIP user agent is configured to validate the state change notification.

4. The apparatus of claim 1, wherein the resource is at least one of a telephone resource, a fax resource, a voicemail system resource, a speakerphone resource, a push-to-talk resource, a video resource, and a data communications resource.

5. The apparatus of claim 1, further comprising:

a timer configured to detect a SIP keep alive timeout, wherein the failover engine is further configured to transmit a SIP message to a backup proxy configured to request a line card to update routing information.

6. The apparatus of claim 5, wherein the SIP message at least one of a SIP RE-INVITE message and a SIP UPDATE message.

7. The apparatus of claim 1, further comprising:

a SIP message generator configured to generate a SIP message;

a fingerprint generator configured to generate a fingerprint based on at least one field of the SIP message; and

a packet transmitter configured to transmit the SIP message over a SIP proxy server configured to validate the fingerprint and detect based on the fingerprint that a source of the SIP message is affiliated with the license.

8. A method for sharing a resource, comprising:

subscribing to a first turret system to share the resource;

receiving a state change notification corresponding to the resource, from the turret system; and

inviting the turret system to initiate a connection to the resource.

9. The method of claim 8, further comprising:

validating the state change notification.

10. The method of claim 8, further comprising:

detecting a SIP keep alive timeout; and

transmitting a SIP message to a backup proxy configured to request a line card to update routing information.

11. The method of claim 8, further comprising:

generating a SIP message;

generating a fingerprint based on at least one field of the SIP message; and

transmitting the SIP message over a SIP proxy server configured to validate the fingerprint and detect based on the fingerprint that a source of the SIP message is affiliated with the license.

12. A computer-readable medium having stored thereon sequences of instructions, the sequences of instructions including instructions which when executed by a computer system causes the computer system to perform:

subscribing to a first turret system to share a resource;

receiving a state change notification corresponding to the resource, from the turret system; and

inviting the turret system to initiate a connection to the resource.

13. The computer-readable medium according to claim 12, further comprising:

validating the state change notification.

14. The computer-readable medium according to claim 12, further comprising:

detecting a SIP keep alive timeout; and

transmitting a SIP message to a backup proxy configured to request a line card to update routing information.

15. The computer-readable medium according to claim 12, further comprising:

generating a SIP message;

generating a fingerprint based on at least one field of the SIP message;

transmitting the SIP message over a SIP proxy server configured to validate the fingerprint; and

detecting based on the fingerprint that a source of the SIP message is affiliated with the license.

16. A system for sharing a resource, comprising:

means for subscribing to a first turret system to share the resource;

means for receiving a state change notification corresponding to the resource, from the turret system; and

means for inviting the turret system to initiate a connection to the resource.

17. The system of claim 16, further comprising:

means for validating the state change notification.

18. The system of claim 16, further comprising:

means for detecting a SIP keep alive timeout; and

means for transmitting a SIP message to a backup proxy configured to request a line card to update routing information.

19. The system of claim 16, further comprising:

means for generating a SIP message;

means for generating a fingerprint based on at least one field of the SIP message;

means for transmitting the SIP message over a SIP proxy server configured to validate the fingerprint; and

means for detect based on the fingerprint that a source of the SIP message is affiliated with the license.
