I would do something like this, as your hidden fields are dynamic:

add a class to your link:

<a class="link-call" href="/Call/@Model.id">Link To Call</a>

Note that your href should be something like

href="@Url.Action("Index", "Call", { id  = @Model.id })"

and then, using jQuery, you can easily fillup your link and make that request.

$(function() {

    $(".link-call").click(function(evt) {

        evt.preventDefault; // don't jump to /Call/2 automatically

        var url = $(this).attr("href") + "?"; // this will hold /Call/2?

        // append your hidden fields
        url += "hf1=" + $("#hf_001").val();
        url += "&hf2=" + $("#hf_002").val();
        url += "&hf3=" + $("#hf_003").val();

        // make the call
        document.location.href = url;
    });

});

your controller might look like this

public ActionResult Index(int id, string hf1, string hf2, string hf3)
{

}

if your route has the ID you can pick up the ID value from the routes and no need to pass it in the method.
