Global Identifier Mapping for Toll-Free VoIP Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current WiFi calling systems require VoIP clients to be programmed as PBX extensions and users to know the extension number, limiting their ability to make and receive calls globally without incurring tolls, and existing solutions are not cost-effective for carriers or users.
Innovation Solution
A system that maps global identifiers to local network identifiers, allowing calls to be routed through a local network, eliminating the need for internal knowledge of PBX dialing plans and enabling VoIP clients to use global numbers for communication, translating phone numbers to IP addresses for call completion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If VoIP clients are programmed as PBX extensions, then calls can be routed through the local network, but users must know the extension number and cannot use global numbers
Solution Approach 1:
The patent introduces a phone exchange as an intermediary component that mediates between global identifiers and local PBX extensions. The phone exchange receives calls addressed to global numbers, performs number translation to convert global identifiers to internal extensions, and routes the calls through the local network. This intermediary resolves the contradiction by allowing users to dial global numbers while still enabling local network routing.
2Adaptability or versatility
If ENUM service is used for number mapping, then global numbers can be translated to local extensions, but carriers must consult external services and incur additional costs
Solution Approach 1:
The patent extracts the number translation functionality from external ENUM services and implements it locally within the carrier's own phone exchange infrastructure. By building in-house translation capabilities, the carrier eliminates the need to consult external ENUM services for every call, reducing external service dependencies and associated costs while maintaining the ability to translate global numbers to local extensions.
3Ease of operation
If static configuration is used for Force to PBX, then all calls can be routed via PBX, but configuration is complex and does not provide toll bypass for outgoing calls
Solution Approach 1:
The patent implements dynamic call routing that automatically determines whether to route calls through the PBX or allow direct toll bypass based on real-time conditions. Instead of static configuration, the system dynamically evaluates call scenarios and adjusts routing behavior accordingly, enabling both PBX routing for incoming calls and toll bypass for outgoing calls without complex manual configuration.

AI summary
Global identifiers can be dialled 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.
