Reverse Out Dial Bridge for International Call Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telephony systems face quality issues and high costs for international long distance conference calls due to reliance on the lowest cost carrier, which restricts call rerouting and incurs exorbitant fees, making it cost-prohibitive for users to initiate and end calls locally at the international destination.
Innovation Solution
A method utilizing a reverse out dial system that parses call numbers to determine country codes, queries a bridge location database to find the closest designated bridge, and reroutes calls through that bridge for local dialing, eliminating unnecessary carriers and improving call quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the lowest cost carrier is used for international calls, then call cost is reduced, but call quality deteriorates and call reliability worsens
Solution Approach 1:
The patent introduces a bridge server as an intermediary component that mediates between the user and the carrier network. The bridge server receives calls locally at the destination country, eliminating the need for direct international carrier routing. This intermediary approach allows calls to be routed through local infrastructure rather than expensive international carriers, improving both cost efficiency and call quality by using reliable local networks.
2Adaptability or versatility
If carrier networks are used for international calls, then calls can be routed internationally, but call cost increases and call flexibility is reduced
Solution Approach 1:
The patent segments the international calling process into two distinct parts: (1) local call setup at the user's location, and (2) local call termination at the destination country via a bridge server. This segmentation eliminates the need for continuous international carrier routing, allowing each segment to use cost-effective local networks while maintaining the ability to reach international destinations.
3Ease of operation
If international calls are redirected via carrier networks, then calls can reach international locations, but legal compliance issues arise and call cost increases
Solution Approach 1:
The bridge server acts as a legal intermediary that enables international calls to originate and terminate locally without violating international calling regulations. By having the bridge server place local calls within the destination country, the system complies with legal requirements while avoiding expensive international carrier fees. The bridge server mediates between the user's international number and the local destination network.

AI summary
An example home bridge may perform receiving an out dial call from a user, parsing a call number to determine a country code, querying a bridge location database to determine a closest designated bridge to a country associated with the country code, providing to the designated bridge out dial data for the call, and lending the out dial call at the designated bridge.
