Topic awaiting preservation: SOAP call response is a blank page (Page 1 of 1)

trying to do Hello World example SOAP call to Magento after creating my Magento user/role for API use and all I get is a blank page response even though a quick check of phpinfo shows I have SOAP enabled...any ideas folks?

Does Magento redirect all it's php errors - check that file.
What happens when you visit the service url directly?

I fixed it!

First I ssh'd into the machine and ran 'php soapcall.php' and realized from the results that the machine wasn't resolving this subdomain internally so I added the subdomain to the /etc/hosts file and then then I was able to make the SOAP call successfully.
