Troubleshoot Cisco UC Integration for Microsoft Lync

The section contains information on resolving common issues with Cisco UC Integration for Microsoft Lync.

Configuration Issues

TFTP and CCMCIP Server Configuration Not Working

Problem description: The TFTP and CCMCIP server values specified in the configuration file are not used by the application.

Resolution: The TFTP and CCMCIP servers can be configured using the configuration file or through registry key settings. Ensure that the misconfigured values are not specified in a registry setting. Registry key values for the TFTP and CCMCIP servers take precedence over the configuration file on a key by key basis. See Phone Parameters for more information on this feature. Registry key values for TFTP and CCMCIP servers are only supported at this time.

Configuration File Is Not Downloaded from the TFTP Server

Problem description: Cisco UC Integration for Microsoft Lync does not download the configuration file from the TFTP server. The configuration file is not available in the installation directory after you start Cisco UC Integration for Microsoft Lync.

Resolution:
  1. Restart your TFTP server.
  2. Check the name of your configuration file.
    Remember:
    • The name of the configuration file is case sensitive.
    • The global configuration filename must be jabber-config.xml.
  3. Ensure your corporate firewall does not prevent Cisco UC Integration for Microsoft Lync from downloading the configuration file.
  4. Host the configuration file on your TFTP server as follows:
    1. Open the Cisco Unified OS Administration interface.
    2. Select Software Upgrades > TFTP File Management.
    3. Select Upload File.
    4. Select Browse in the Upload File section.
    5. Select the configuration file on the file system.
    6. Leave the value of the Directory text box empty to host the configuration file in the default directory of your TFTP server.
    7. Select Upload File.

Cisco UC Integration for Microsoft Lync Does Not Read the Configuration File

Problem description: You host a global or group configuration file on your TFTP server. Cisco UC Integration for Microsoft Lync downloads the configuration file and saves it in the appropriate installation directory. However, Cisco UC Integration for Microsoft Lync does not apply any settings you specify in the configuration file.

Resolution: Ensure the XML in the configuration file is valid. Cisco UC Integration for Microsoft Lync configuration files must do the following:
  • Use utf-8 encoding.
  • Contain only valid XML character entities. For example, use & instead of &.Open your configuration file in Microsoft Internet Explorer to determine if any characters or entities are not valid. If Internet Explorer displays the entire XML structure, your configuration file does not contain invalid characters or entities. If Internet Explorer displays only part of the XML structure, your configuration file most likely contains invalid characters or entities.
  • Contain a valid structure. Ensure parameters are nested under the correct elements. The following XML snippet shows the basic structure of a configuration file:
    <?xml version="1.0" encoding="utf-8"?>
    <config version="1.0">
     <Client>
      <parameter_name>value</parameter_name>
     </Client>
     <Directory>
      <parameter_name>value</parameter_name>
     </Directory>
     <Policies>
      <parameter_name>value</parameter_name>
     </Policies> 
    </config>

Cisco UC Integration for Microsoft Lync Uses Old Configuration Settings

Problem description: Cisco UC Integration for Microsoft Lync is not using the current configuration settings. You change settings in a configuration file and host it on your TFTP server. However, Cisco UC Integration for Microsoft Lync uses the settings from the previous version of the configuration file.

Resolution:
  1. Restart your TFTP server.
  2. Open the configuration file in your browser to verify the settings. Typically, you can access the configuration file at the following URL: http://tftp_server_address:6970/jabber-config.xml
If restarting your TFTP server does not resolve this issue, it is likely that Cisco UC Integration for Microsoft Lync uses the cached configuration file because it cannot download the current version.

Microsoft Outlook Contacts Are Not Displayed in Search Results

Problem description: Microsoft Outlook contacts are not displayed in search results.

Resolution: Review the following requirements to ensure users can search for and communicate with Microsoft Outlook contacts:
