As per description the client can add multiple number into input box and the API will check it So i added big input box for it and as per description the output will be in table with all checked numbers, I can bring that table on the front end and it will give the result without refreshing the Page, But the Design of home page will be very messy. So, I bought that on another page. and i redirect that form on that page.
And For link this fields can check only one number at a time. And as per job description on voip this portout eligibility check should handle multiple numbers.
