Using regex for validation

I am trying to validate the telephone number using the regix. but it is giving me error:

  $validator=Validator::make($request->all(),[
        'name'=>'required',
        'telephone'=>'regix:^[[0-9]\-\+]{9,15}$|required|unique:telephone',
        'email'=>'unique:telephone',]);

the error is:

Method [validateRegix] does not exist.
