Abstract

A system for (and a method of) selectively establishing communication with one of plural devices associated with a single telephone number during a disaster or disaster recovery period. The method can offer disaster recovery to an enterprise depending upon its size, financial well-being and desired capabilities. For example, the enterprise has the option of owning or renting all of the equipment required so that it may perform disaster recovery on its own and with little outside intervention. The enterprise may own some or none of the necessary equipment and contract with a service bureau so that the bureau provides recovery equipment when needed. The system also provides for roll call, priority preemption and seamless switching services to and from circuit and packet communication devices.

Claims

1. A method of providing a recovery telecommunication service to an enterprise operating a first telecommunication network connected to a first wireless connection unit, said method comprising the steps of:

detecting whether a disaster has occurred at a first location that has rendered the first telecommunication network inoperable;

if the first telecommunication network is inoperable, enabling a second wireless connection unit to serve as a recovery server to operate the first telecommunication network; and

servicing a communication destined for a dialed telephone extension of the first telecommunication network by rerouting the destined communication for the first telecommunication network to the second wireless connection unit

wherein the second wireless connection unit reroutes the destined communication according to a database within the second wireless connection unit having a plurality of telephone extensions associated with the first wireless connection unit, the database being substantially the same as another database within the first wireless connection unit.

2. The method of claim 1, wherein the second wireless connection unit is operated by the enterprise.

3. The method of claim 1, wherein the second wireless connection unit is operated by an entity other than the enterprise.

4. The method of claim 1, wherein the second wireless connection unit is operated by a service bureau.

5. The method of claim 4, wherein the service bureau charges a fee to the enterprise for maintaining the second database on behalf of the enterprise.

6. The method of claim 4, wherein the service bureau charges a fee to service the communication via the second wireless connection unit.

7. The method of claim 1, further comprising the steps of:

identifying the dialed telephone extension from the serviced communication;

using the identified dialed telephone extension to retrieve a first communication device number associated with the one of the first communication devices and a second communication device number associated with a second communication device; and

routing the serviced communication to at least one of said first and second communication device numbers.

8. The method of claim 1, wherein the second database comprises a plurality of telephone extensions each associated with a first communication device connected to the first telecommunication network and a second communication device and at least one user preference associated with each of the plurality of telephone extensions.

9. The method of claim 8, further comprising the steps of:

identifying the dialed telephone extension from the serviced communication;

using the identified dialed telephone extension to retrieve a first communication device number associated with the first communication device, a second communication device number associated with the second communication device and at least one user preference; and

routing the serviced communication to at least one of said first and second communication device numbers based on the user preference.

10. The method of claim 8, further comprising the steps of:

identifying the dialed telephone extension from the serviced communication;

using the identified dialed telephone extension to retrieve a first communication device number associated with the first communication device, a second communication device number associated with the second communication device and at least one user preference; and

directing the serviced communication in accordance with the user preference to at least one destination communication number, wherein the at least one destination communication number is selected from a group including the first arid second communication device numbers and a voice mailbox number.

20. The method of claim 1, further comprising the step of copying a first database of the first wireless connection unit into a second database in the second wireless connection unit, the second database comprising a plurality of telephone extensions each being associated with a respective first communication device connected to the first telecommunication network.

11. A method of providing a recovery telecommunication service to an enterprise operating a first telecommunication network, said method comprising the steps of:

detecting whether an event has occurred that has rendered the first telecommunication network inoperable;

enabling a wireless connection unit connected to the first telecommunication network to serve as a recovery server;

maintaining a database, within the wireless connect unit, of telephone extensions of the first telecommunication network, each extension being associated with a first communication device connected to the first telecommunication network and a second communication device; and

servicing a communication destined for an extension of the first telecommunication network by rerouting the destined communication to the wireless connection unit using the maintained extensions when the communication cannot reach its destination through the inoperable first telecommunication network.

12. The method of claim 11, wherein the wireless connection unit is operated by an entity other than the enterprise.

13. The method of claim 11, wherein the wireless connection unit is operated by a service bureau.

14. The method of claim 13, wherein the service bureau charges a fee to the enterprise for maintaining the database on behalf of the enterprise.

15. The method of claim 13, wherein the service bureau charges a fee to service the communication via the wireless connection unit.

16. The method of claim 11, further comprising the steps of:

identifying the extension from the serviced communication;

using the identified extension to retrieve a first communication device number associated with the first communication device and a second communication device number associated with the second communication device; and

routing the serviced communication to at least one of said first and second communication device numbers.

17. The method of claim 11, wherein the database further comprise at least one user preference associated with each of the plurality of telephone extensions.

18. The method of claim 17, further comprising the steps of:

identifying the extension from the serviced communication;

using the identified extension to retrieve a first communication device number associated with the first communication device, a second communication device number associated with the second communication device and at least one user preference; and

routing the serviced communication to at least one of said first and second communication device numbers based on the user preference.

19. The method of claim 17, further comprising the steps of:

identifying the extension from the serviced communication;

using the identified extension to retrieve a first communication device number associated with the first communication device, a second communication device number associated with the second communication device and at least one user preference; and

directing the serviced communication in accordance with the user preference to at least one destination communication number, wherein the at least one destination communication number is selected from a group including the first and second communication device numbers and a voice mailbox number.
