Is it possible ? or any other approach ?

    Yes, it's possible, that's the default behaviour for a multiple cardinality field. What problem are you having?

    The cardinality is part of the settings for every field type - edit any field, scroll to the bottom, and change "Number of Values" to "Unlimited"

  • Why not have one field for the primary number, cardinality 1, and another optional field with unlimited cardinality for secondary numbers? Oct 24, 2013 at 8:29

I think you can use the Field Collection module.
