Troubleshooting Cisco Unified IP Phone

Service Applications

This chapter contains the following sections:

•Troubleshooting Tips

•XML Parsing Errors

•Error Messages

Troubleshooting Tips

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 another web browser

•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 3, “CiscoIPPhone XML Objects” for more information.

•Validate XML applications developed prior to Cisco Unified IP Phone firmware release 8.3(2) against the more recent XML parser (see the “Updated XML Parser and Schema Enforcement” section on page B-1for details). Some of examples of the types of errors you might encounter include:
