Email Notification Service for VoIP Call Disposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication networks like VoIP and SoIP, users without caller ID and voicemail services may not be aware of missed calls, as they do not receive notifications for unanswered or busy calls, leading to missed opportunities and unnecessary interruptions.
Innovation Solution
Implementing an email notification service that registers users for call disposition alerts, using Call Detail Records and application servers to identify and notify calling and called parties about unanswered or busy calls, providing information such as caller and called party details, and call disposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If users use basic phone service without caller ID and voicemail, then device complexity is reduced and ease of operation is improved, but information completeness deteriorates as users cannot be notified of missed or busy calls
Solution Approach 1:
The patent introduces an email notification service as an intermediary between the telephony system and the user. This intermediary captures call disposition information from the telephony network and delivers it to users via email, resolving the information loss without requiring direct complexity in the user's phone device.
2Loss of information
If users enable email notification service for all calls, then information completeness is improved, but use of energy increases due to continuous monitoring and email transmission
Solution Approach 1:
The system implements selective email notifications based on call disposition types. Instead of notifying for every call, it specifically targets unanswered and busy calls, providing sufficient information without the excessive energy consumption of universal notification.
3Measurement precision
If the system monitors all call dispositions in real-time, then measurement precision is improved, but device complexity and processing requirements increase
Solution Approach 1:
The patent extracts only the essential call disposition information (unanswered, busy) from the complete call signaling data. This extraction approach achieves sufficient measurement precision for notification purposes without requiring complex real-time monitoring of all call parameters.
4Loss of information
If users without voicemail service are away from the phone, then ease of operation is maintained, but loss of information occurs as they cannot determine who has called
Solution Approach 1:
The email notification service automatically captures and delivers caller information without requiring user action. When away from the phone, users receive self-generated email notifications with caller details, maintaining ease of operation while eliminating information loss about missed calls.
Data Source
AI summary
A method and apparatus for providing email notification for called and/or calling parties of a call placement are disclosed. The method enables a packet network service provider, e.g., a VoIP or SoIP service provider, to register customers for email notification service, to obtain the disposition of calls from Call Detail Records (CDRs), call control elements or application servers that have access to call signaling information in real time, to identify calls that resulted in ringing without an answer or busy disposition, and to determine whether or not the called and/or calling party subscribed to the email notification service. If the calling and/or called party subscribe to the notification service, the service provider sends an email notification to the calling and/or called party containing the caller and called party information, the time of the call, the disposition of the call and the like.
