I have tried to import the WSDL
http://test2messaging.easylink.com/JobSubmit/2011/01?WSDL
but it only makes object its does create the JobSubmit service.
I grabbed you sample code for single send and if the service was there I might be able compile all the other object were importeed.
Do you have a simple rest server so I can leave all SOAP nonsense behind? Something like a swagger interface that you test the api online?
Please email as I doubt I'll ever be able to find my message again since there is no category for easylink or fax
