CISCO 7960 IP Telephone Services

I’m trying to get a simple services XML page to display on my Cisco IP telephone with no luck. I have set the to be some web page on my Apache web service, let’s call it index.xml. No matter what I put in the web page, the Cisco phone reports an XML parse error! Could someone give me a hint as to what I am doing wrong?

If I set the to be index.html AND I just put plain text in the index.html file, the text is displayed on the telephone.
