Phone Number Adjustment via Automatic Digit Prepending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telephone exchanges often incorrectly provide phone numbers, leading to rejected calls due to incorrect dialing sequences, and caller identification information may also contain errors, causing issues in establishing communication sessions.
Innovation Solution
A method and system that adjust phone numbers by prepending a digit to correct the dialing sequence, allowing for automatic storage and future use in telephonic devices, enabling correct redialing and contact management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If phone numbers are provided by telephone exchanges, then communication routing is enabled, but the phone numbers may be incorrect leading to call rejections
Solution Approach 1:
The system monitors incoming calls and detects when calls are rejected due to incorrect phone numbers. This feedback loop allows the system to identify erroneous phone numbers from the telephone exchange and automatically correct them by prepending the appropriate digit (e.g., '1') before storing the corrected number for future use.
Solution Approach 2:
The system performs preliminary correction of phone numbers by automatically prepending the required digit before the number is stored in contacts or used for outgoing calls. This preliminary action prevents call rejection before it occurs, ensuring that all stored phone numbers are in the correct format.
2Ease of operation
If caller identification information is used, then incoming call identification is enabled, but the information may contain errors causing communication issues
Solution Approach 1:
The system uses feedback from attempted calls to verify the accuracy of stored phone numbers from caller identification. When a call is rejected, the system recognizes this as feedback indicating an error in the stored number and automatically corrects it.
Solution Approach 2:
The system automatically detects and corrects erroneous phone numbers without requiring user intervention. When an incorrect number is detected through call rejection, the system self-corrects by prepending the appropriate digit and updating the stored number autonomously.
3Device complexity
If phone numbers are stored without adjustment, then storage simplicity is maintained, but automatic redialing fails due to incorrect dialing sequences
Solution Approach 1:
The system performs preliminary adjustment of phone numbers by automatically prepending the required digit during the storage process. This ensures that all stored numbers are pre-formatted correctly, enabling successful automatic redialing without adding complexity to the storage mechanism itself.

AI summary
A method to adjust a phone number is provided. The method may include receiving a first phone call at a telephonic device and obtaining a phone number from the first phone call. In some embodiments, the phone number may identify an origin of the first phone call. The method may further include prepending a digit to the phone number and storing the phone number with the prepended digit in a memory in the telephonic device. In some embodiments, the method may further include using the stored phone number to initiate automatic placement of the second phone call.
