duplicate phone number detection when multiple phone number is added

[L-rrrr]

Give the design of the product, multiple phone numbers, let's say 3, can be inputted in the phone number field. However, I might have forgotten I have keyed in this person and input the same person but with only 2 duplicate phone numbers. In this case, the app will not detect this as a duplicate.

Suggestion: there should be a detection if a new valid phone number matches a substring of another person's phone number.

Team's Response

Thank you for bringing this up. After further consideration, we believe this issue falls under Planned Enhancement 9, where we have outlined plans to implement duplicate phone number checks in a future iteration. Additionally, implementing substring checks for phone numbers may lead to unintended bugs and complications. Given our current design choices, verifying whether one person's phone number contains another's would be overly complex and impractical.

:question: Issue response

Team chose [response.Rejected]

• [x] I disagree

Reason for disagreement: The following picture clarifies what is considered not in scope on CS2103T website:

The following picture is the duplicate handling specified in UG:

• Firstly, this issue does not fall under planned enhancements 9 because planned enhancement 9 addresses the issue of stripping country code and annotations when checking for duplicate phone numbers. The issue I mentioned is when a person's phone number is a substring of another person's phone number, the application fails to detect this duplicate.
• Secondly, I understand it might be a bit hard to implement the substring checking at this juncture, but this issue is not mentioned in UG, not mentioned in future enhancements in DG, and the app does not warn the user when a user attempts to try this feature.
• Therefore, I believe this issue does not qualify for not in scope.
