Gagal migrasi table one to one relationship pada laravel 5.8

saya ingin membuat Eloquent relationship one to one pada laravel tetapi terjadi masalah. disini saya ingin menguhubungkan antara id:siswa dengan id_siswa:telepon dan ketika saya migrate terjadi error seperti ini

Illuminate\Database\QueryException  : SQLSTATE[HY000]: General error: 1005 Can't create table `db_siswakuapp`.`
telepon` (errno: 150 "Foreign key constraint is incorrectly formed") (SQL: alter table `telepon` add constraint `t
elepon_id_siswa_foreign` foreign key (`id_siswa`) references `siswa` (`id`) on delete cascade on update cascade)

ini kode table siswa

<?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateTableSiswa extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('siswa', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('nisn', 4)->unique();
            $table->string('nama_siswa', 30);
            $table->date('tanggal_lahir');
            $table->enum('jenis_kelamin', ['L', 'P']);
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('siswa');
    }
}

dan ini kode table telepon yang tidak bisa dimigrate

<?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateTableTelepon extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('telepon', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->Integer('id_siswa')->primary('id_siswa');
            $table->string('telepon')->unique();
            $table->foreign('id_siswa')->references('id')->on('siswa')->onDelete('cascade')->onUpdate('cascade');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('telepon');
    }
}
