Toll-Free Call Routing via Application Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Toll-free services are not consistently available to customers using dedicated trunk groups in telecommunications networks, as routing bypasses application servers that provide features like concurrent calling and overflow routing, limiting feature availability and functionality.
Innovation Solution
Implementing a method and system where toll-free communications are routed through an application server, which applies features such as concurrent calling and overflow routing, regardless of the routing method, by associating a trunk group identifier or dialed toll-free number with the communication request, ensuring all customers, including those with dedicated trunk groups, receive full toll-free features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If toll-free communications are routed through a dedicated trunk group, then routing efficiency is improved, but toll-free service features become unavailable
Solution Approach 1:
The patent introduces an application server as an intermediary component in the call routing path. When a toll-free call is received, the system routes the call through the application server which then forwards it to the dedicated trunk group. This intermediary approach allows the call to benefit from both the efficient dedicated trunk group routing and the toll-free service features provided by the application server, resolving the contradiction between routing efficiency and feature availability.
2Speed
If toll-free communications bypass the application server for dedicated trunk group customers, then call handling speed is improved, but service functionality is reduced
Solution Approach 1:
The system performs preliminary identification of toll-free calls and pre-establishes routing instructions that direct these calls through the application server even when the destination is a dedicated trunk group. This preliminary action ensures that toll-free feature processing is initiated before the call reaches the trunk group, maintaining both speed and functionality by automating the routing decision and feature application in advance.

AI summary
Aspects of the present disclosure involve systems, methods, computer program products, and the like, for providing one or more toll-free services to a customer of an enterprise telecommunications network environment. In particular, the toll-free services may be provided to the customer by one or more application servers associated with the network. Through use of the systems and methods of the present disclosure, such services may be provided for the customer regardless of the method of routing through the network requested by the customer. For example, the toll-free communication may be transmitted through the network based on a destination telephone number associated with the customer. In another example, the toll-free communication is transmitted through the network based on a destination trunk group associated with the customer.
