How to do a ManytoMany or ManyToOne Doctrine Neo4j - php

Question

I'm learning how to work with Neo4j and Doctrine OGM, and I'm having problems with my source code. I don't know how to use manytomany because I'm just starting learn. When I save I see:
Catchable fatal error: Argument 1 passed to Entity\Empresas::setTelefone() must be an instance of Entity\Entity\Telefones, string given, called in /Applications/MAMP/htdocs/neo4j/n4j/save.php on line 17 and defined in /Applications/MAMP/htdocs/neo4j/n4j/Empresas.php on line 50
My Empresas.php entity
namespace Entity;
use HireVoice\Neo4j\Annotation as OGM;
use Doctrine\Common\Collections\ArrayCollection;
/**
* All entity classes must be declared as such.
*
* #OGM\Entity(labels="Empresas")
*/
class Empresas
{
/**
* The internal node ID from Neo4j must be stored. Thus an Auto field is required
* #OGM\Auto
*/
protected $id;
/**
* #OGM\Property
* #OGM\Index
*/
protected $nome;
/**
* #OGM\Property
*/
protected $keywords;
/**
* #OGM\ManyToOne(relation="tem_telefone")
*/
protected $telefone;
function getID(){
return $this->id;
}
function setNome($nome){
$this->nome = $nome;
}
function setKeywords($keywords){
$this->keywords = $keywords;
}
public function getTelefone() {
return $this->telefone;
}
public function setTelefone(Entity\Telefones $telefone) {
$this->telefone = $telefone;
}
}`
My Telefones.php Entity
<?php
namespace Entity;
use HireVoice\Neo4j\Annotation as OGM;
use Doctrine\Common\Collections\ArrayCollection;
/**
* All entity classes must be declared as such.
*
* #OGM\Entity(labels="Empresas")
*/
class Telefones
{
/**
* The internal node ID from Neo4j must be stored. Thus an Auto field is required
* #OGM\Auto
*/
protected $id;
/**
* #OGM\Property
* #OGM\Index
*/
protected $telefone;
function getID(){
return $this->id;
}
}
And my Save.php Entity
<?php
require 'bootstrap.php';
require 'Empresas.php';
require 'Telefones.php';
$repo = $em->getRepository('Entity\\Empresas');
$empresa_container = $em->find('Entity\\Empresas', "22");
$telefones = new Entity\Telefones();
$empresa = new Entity\Empresas;
$empresa->setNome("nome");
$empresa->setKeywords("keywords");
$empresa->setTelefone("telefone");
$em->persist($telefones);
$em->persist($empresa);
$em->flush();
echo $empresa->getId();
Error
