How to Insert N Records in a Single Stored Procedure Call

Question

How would I accomplish being able to insert an unknown number of records into the database using a single stored procedure call?

Say I have this table definition:

CREATE TABLE PHONE(
    PhoneID int identity(1,1),
    PhoneNumber varchar(20),
    PersonID int
)

And I have the following insert stored procedure:

CREATE PROCEDURE dbo.usp_Phone_Insert
    @PhoneNumber varchar(20),
    @PersonID int
AS

INSERT 
    PHONE 
VALUES
    (@PhoneNumber, @PersonID)

How would I be able to transform this to insert any number of records in a single call to this stored procedure?

I have some blog posts with code samples that address this topic.
