You probably want a polymophic association:

class Telefone < ActiveRecord::Base
belongs_to :owner, :polymorphic => true
end

class Person < ActiveRecord::Base
has_many :telefones, :as => :owner
end

class Company < ActiveRecord::Base
has_many :telefones, :as => :owner
end

See the information at
http://guides.rubyonrails.org/association_basics.html#polymorphic-associations
