This chapter contains the following sections:
•XML Parsing Errors
The following tips apply to troubleshooting Cisco Unified IP Phone service applications:
•Microsoft Internet Explorer 5 or higher can display the XML source with its default style sheet.
•Understand that standard IP troubleshooting techniques are important for HTTP errors.
•Externally verify name resolution (Phone has DNS set).
•If DNS is suspected, use IP addresses in URLs.
•Browse the URL in question with Microsoft Internet Explorer or download and verify with Netscape Navigator.
•Use a logged telnet session to verify that the desired HTTP headers are returned (Telnet to the server on port 80; then, enter get /path/page).
XML Parsing Errors
The following tips apply to troubleshooting XML parsing errors in Cisco Unified IP Phone services applications:
•Verify the object tags (the object tags are case sensitive).
•Verify that "&" and the other four special characters are used per the restrictions while inside the XML objects. See Chapter 2, "CiscoIPPhone XML Objects" for more information.
The following error messages may appear on the prompt line of the Cisco Unified IP Phone display.
XML Error = XML Parser error (Invalid Object)
XML Error = Unsupported XML Object (not supported by this phone model)
