Description:
------------
5.1.4 appears to be still using __call instead of __soapCall, in at least one place this causes exceptions without error codes to be thrown.



Reproduce code:
---------------
<?php
$wsdl = 'http://vx.valex.com.au/soap/vxsoap.wsdl';

$client = new SoapClient($wsdl);
            
$result = $client->login(array("username" => "fake", "password" => "user"));
?>

Expected result:
----------------
No SoapFaults thrown, or a SoapFault is thrown with a meaningful error.

Actual result:
--------------
---------- php ----------

Fatal error: Uncaught SoapFault exception: [SOAP-ENV:Server] SoapFault::__construct() [<a href='function.SoapFault---construct'>function.SoapFault---construct</a>]: Invalid parameters. Invalid fault code. in C:\vx\tests\unit\soap\LoginTest.php:42
