c# linq to xml take one element of many

I have this code

List<Customer> customersList =
                (
                    from e in XDocument.Load(file).Root.Elements("cust")
                    select new Customer
                    {
                        CustomerID = (int)e.Attribute("custid"),
                        FirstName = (string)e.Attribute("fname"),
                        LastName = (string)e.Attribute("lname"),
                        ShowsNumber = (int)e.Attribute("count_noshow"),
                        VisitNumber = (int)e.Attribute("count_resos"),
                        Cancellation = (int)e.Attribute("count_cancel"),

                    }).ToList();

as you see, I am extracting the attributes, but I have three (sometimes four) elements of phone I want to extract the first element of them.

I tried this:

(string)e.Elements

but I don't know what should I do now

could you help me please?
