Abstract

In certain embodiments, a system comprises a connection to a network and an application server providing a cross cluster extension mobility (CCEM) service configured to receive a request from a user to log into the CCEM service from a telephony device connected to the network, prompt the user via the telephony device to provide a user ID, determine whether the user is logging in from a home cluster or a remote cluster, and perform a local extension mobility login for the user.

Claims

1. A communication device, comprising:

a graphical user interface (GUI);

a plurality of programmable soft keys coupled with the GUI; and

internal circuitry configured to invoke a cross cluster extension mobility (CCEM) service for the communication device responsive to a user pressing at least one of the plurality of programmable soft keys.

2. The communication device of claim 1, wherein the plurality of programmable soft keys is configured to enable the user to interact with the CCEM service.

3. The communication device of claim 2, further comprising a first plurality of hard keys configured to enable the user to conduct at least one of call transfer and call hold operations.

4. The communication device of claim 3, further comprising a second plurality of hard keys configured to enable the user to conduct familiar telephonic operation.

5. The communication device of claim 4, wherein at least one of the first and second pluralities of hard keys is further configured to enable the user to interact with the CCEM service.

6. The communication device of claim 5, wherein at least one of the plurality of programmable soft keys and the first and second pluralities of hard keys is configured to enable the user to provide a user ID and a PIN for the CCEM service.

7. The communication device of claim 1, wherein the GUI is configured to provide a web interface.

8. A call manager for a cluster that supports cross cluster extension mobility (CCEM), the call manager comprising:

a network interface configured to receive incoming data from a network and transmit outgoing data to the network;

a processor coupled with the network interface; and

a memory accessible by the processor, wherein the memory is configured to store a user device profile and a configuration file for each of a plurality of phones within the cluster.

9. The call manager of claim 8, wherein the memory is further configured to store telephony control software that provides a plurality of telephony functions to control Internet Protocol (IP) telephony devices.

10. The call manager of claim 9, wherein the plurality of telephony functions comprises a Trivial File Transfer Protocol (TFTP) service.

11. The call manager of claim 10, wherein the TFTP service comprises configuring one or more TFTP parameters to accommodate file transfer between the cluster and another cluster.

12. The call manager of claim 8, wherein the network interface comprises one of an electrical connection, a physical connection, an electromagnetic connection, and a wireless connection.

13. The call manager of claim 8, wherein the processor is configured to provide a telephony device in the cluster with at least one of a local number, Internet Protocol (IP) service, and one or more speed dials for the telephony device in another cluster.

14. A system, comprising:

a connection to a network; and

an application server providing a cross cluster extension mobility (CCEM) service configured to;

receive a request from a user to log into the CCEM service from a telephony device connected to the network;

prompt the user via the telephony device to provide a user ID;

responsive to receiving a valid user ID, determine whether the user is logging in from a home cluster or a remote cluster; and

perform a local extension mobility login for the user.

15. The system of claim 14, wherein the CCEM service is further configured to, responsive to a determination that the user is logging in from the remote cluster, obtain information pertaining to the telephony device and create a temporary device in the home cluster, wherein the information comprises a telephony device name.

16. The system of claim 15, wherein the CCEM service is configured to create the temporary device by giving the telephony device name to the temporary device and then changing the telephony device name for the telephony device.

17. The system of claim 16, wherein the CCEM service is configured to perform the local extension mobility login for the user in the remote cluster.

18. The system of claim 17, wherein the CCEM service is further configured to provide the telephony device with at least one of a local number, Internet Protocol (IP) service, and one or more speed dials.

19. The system of claim 14, wherein the CCEM service is further configured to, responsive to receiving an invalid user ID, send an error message to the user via the telephony device.

20. The system of claim 14, wherein the CCEM service is further configured to perform local extension mobility logout for the user.
