Callback Voice Number for Enterprise Telephony on Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for enterprise voice call routing on mobile devices face challenges in reconciling personal and office phone functionalities, particularly in providing secure and bandwidth-efficient communication, as they require broadband connections for bulk voice data transport, limiting their mobility and flexibility.
Innovation Solution
A method and system that separate enterprise call-control functionality from bulk voice transport, using a callback voice number as a proxy for voice application interaction, allowing secure and efficient call management on mobile devices by establishing a communications session through a telephony switch, enabling rich enterprise telephony over existing voice channels with lower bandwidth requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile handset is used as replacement of office line with direct PBX communication, then robust and flexible functionality is provided, but broadband connection is required which limits mobility
Solution Approach 1:
The system segments the telephony functionality into two parts: call control signaling (handled by mobile device and server) and bulk voice transport (handled by traditional telephony network). This separation allows the mobile device to provide enterprise telephony functionality without requiring broadband connection for voice data transport.
Solution Approach 2:
A server acts as an intermediary between the mobile device and the PBX system. The server receives call requests from the mobile device, translates them into appropriate telephony commands, and manages the callback mechanism. This intermediary enables the mobile device to access enterprise telephony resources without direct PBX connection.
2Adaptability or versatility
If mobile phone is used to extend office line, then users can receive calls on cellular phones, but additional functionality requires complex authentication and dialing procedures
Solution Approach 1:
The system implements self-service through the callback mechanism. When a user wants to place a call, they initiate a request to the server, which automatically places a callback to the user's mobile device. The user simply answers the incoming call to establish the connection, eliminating the need for manual dialing or complex authentication during the call setup process.
3Reliability
If secure channel over VPN is used for direct PBX communication, then secure enterprise telephony is provided, but broadband connection is required which increases bandwidth requirements
Solution Approach 1:
The system extracts the bulk voice data transport from the secure VPN channel and moves it to the traditional telephony network. Only lightweight call control signaling remains on the VPN channel between the mobile device and server. This extraction dramatically reduces the bandwidth requirements for secure enterprise telephony while maintaining security for control functions.

AI summary
A method of facilitating telecommunication functionality on a mobile device. The method includes receiving a request for a telecommunications transaction from the mobile device and retrieving a callback identifier for a user of the mobile device. The method also includes executing the telecommunications transaction, wherein executing the transaction includes establishing a communications session that includes a callback telephony endpoint represented by the callback identifier and at least one target telephony endpoint, wherein a portion of the communications session that includes the callback telephony endpoint is established at least in part by making an outbound call from a telephony switch.
