Abstract

Global identifiers can be dialed from anywhere in the world. The present application relates to a call processing telecommunication system and methods thereof in a wireless network for connecting communication devices. The integrated system can resolve issues with global identification using internal identifiers. In one illustrative embodiment, the global identifiers can be registered and mapped to an internal number such that the global numbers can be used to contact individuals. When a call is placed by a communication device, the internal identifier of the calling device can be tied back to the global identifier, which then provides access to the IP address of the VoIP client to complete the call. For incoming calls, the global identifiers can be translated into an internal identifier to route the call through the network.

Claims

1. A method for establishing communication with a device having a global identifier, said method comprising:

receiving a communication request for a device along with a global identifier corresponding to said device;

associating said global identifier with an internal identifier and IP address of said device;

routing said communication request using said internal identifier; and

connecting said communication request with said device using said IP address.

2. The method of claim 1, comprising registering said device by attaching said global identifier with said internal identifier and said IP address on a phone exchange.

3. The method of claim 1, wherein said communication request is received from a calling device.

4. The method of claim 3, wherein routing said communication request using said internal identifier comprises directing said communication request to an egress point associated with said device.

5. The method of claim 3, wherein associating said global identifier with said internal identifier and said IP address comprises using a lookup table on a phone exchange.

6. The method of claim 1, wherein said communication request is received from said device.

7. The method of claim 6, wherein said device forwards said global identifier.

8. The method of claim 7, wherein associating said global identifier with said internal identifier and said IP address comprises using a lookup table on a phone exchange.

9. A phone comprising:

at least one processor; and

a memory operatively coupled to said processor, said memory storing program instructions that when executed by said processor, causes said processor to;

receive a communication request over a phone network;

forward phone information to a network service, wherein said network service determines whether said phone is associated with an IP address using said phone information; and

connect said communication request with said phone through said IP address using a wireless network depending on said determination.

10. The phone of claim 9, wherein said memory storing program instructions, when executed by said processor, causes said processor to connect said communication request with said phone over said phone network depending on said determination.

11. The mobile phone of claim 10, wherein said phone network is a plain old telephone service network.

12. The phone of claim 10, wherein said memory storing program instructions, when executed by said processor, causes said processor to display an error depending on said determination.

13. The phone of claim 9, wherein said phone information comprises a global identifier.

14. The phone of claim 9, wherein said memory storing program instructions, when executed by said processor, causes said processor to configure said phone with said network service.

15. The phone of claim 14, wherein configuring said phone with said network service comprises providing said IP address along with port and contact information.

16. The mobile phone of claim 9, wherein connecting said communication request with said phone through said IP address comprises a peer-to-peer connection.

17. A system comprising:

a phone exchange for establishing a connection between a calling device and a called device;

wherein said phone exchange receives a dialed number for said called device from said calling device, said phone exchange routing said connection using an extension of said phone exchange when said dialed number translates to said extension and establishing said connection over a wireless network otherwise providing said connection through a phone network.

18. The system of claim 17, wherein said phone exchange comprises a lookup table for storing associations between said dialed number and phone exchange.

19. The system of claim 17, wherein said calling device and called device are configured with said phone exchange.

20. The system of claim 17, wherein said calling device installs a VoIP client and registers with said phone exchange.
