This is a feature :-)

The problem is that some webservices need empty the request when no parameters 
(ie. jboss), and some other do expect an empty tag (ie. oracle).

That's why this version added an optional parameter to SoapClient constructor: 
soap_server. 

Specify "oracle" as the server, and it would send the empty Body tag:
SoapClient(..., soap_server="oracle")

Please let me know if this works, and if you can attach the full trace (with 
http headers showing what kind of server you are using)

With soap_server='oracle' it did work yes, I got this body:

<soap:Body>
    <RecuperaEstadoDispositivos xmlns="tns">
    </RecuperaEstadoDispositivos>
</soap:Body>

Thanks for the tip !

It's still not a empty element, the above has a body of "\n  ". Ie in xml these 
are not equvalent:

 -  '<foo> </foo>'
 -  '<foo></foo>'

The xml string should be something like:
<%(soap_ns)s:envelope xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" 
    xmlns:xsd="http://www.w3.org/2001/xmlschema" 
    xmlns:%(soap_ns)s="%(soap_uri)s"><%(soap_ns)s:header/><%(soap_ns)s:body><%(method)s xmlns="%(namespace)s"></%(method)s></%(soap_ns)s:body></%(soap_ns)s:envelope>"""

The above works for me.

Also, instead of using an argument of soap_server, use a meaningful name? Ie. i 
need the same but it's not an oracle server.
 (Poor) example: always_include_element=True
