Exclude characters in bind model Asp.net MVC

Hi I have a field CellPhone of type int in my model.

In the view I have a javascript mask in my CellPhone field. When the client send the post of the page I receive something like that:

555-4789

But this value is not valid value for a int type. There is anyway to notify the model binder that I want to "clean" the number by removing the character '-' before binding happens?

Maybe a DataAnnotation or something else?

Use custom model binder for that-

public class yourmodel
{
public int cellphone{get;set;}
}

Define custom model binder as
public class CustomBinder : IModelBinder
{
    public object BindModel(ControllerContext controllerContext, 
                            ModelBindingContext bindingContext)
    {
        HttpRequestBase request = controllerContext.HttpContext.Request;

        string[] phoneArray= request.Form.Get("CellPhone").split('-');

        string phone=phoneArray[0]+phoneArray[1];

        return new yourmodel
                   {
                       cellphone= convert.ToInt32(phone)
                   };
    }
} 


then in app_start register new created binder as
protected void Application_Start()
{

    ModelBinders.Binders.Add(typeof(yourmodel), new CustomBinder());
}

and in controller 
[HttpPost]
public ActionResult Index([ModelBinder(typeof(CustomBinder))] yourmodel model)
{

    //..processing code
}
