Extension of the call window via the estos SDK should only be carried out with the appropriate expertise!

A reference solution is included in the ProCall Enterprise SDK to extend the call window with a link that creates a callback notification via email.


The component required to use the feature can be found in the SDK – package under

  • .\COM\Script\CWJournalForward.htm

This file must be copied to a location that can be reached by all relevant ProCall clients via a network share, e.g. \<server>\<share>\procall (read permissions are sufficient).

The HTML document contains a link, which is formed by Javascript with the relevant contact data, the note and a speaking e-mail subject. The help in the SDK, which is only available in English, contains further hints under the keywordConversationWindow.

To include the extension in the ProCall call window, a corresponding registry key must be set on each relevant client.

The required key is 

  • ConversationWindowURL
  • Type: REG_SZ
  • Value: URL to HTML document, e,g, http://<server>/<path>/CWJournalForward.htm

and can be set under the following keys:

  • HKEY_CURRENT_USER\Software\Policies\ESTOS\UCServer4\CtiMain
  • HKEY_CURRENT_USER\Software\ESTOS\UCServer4\CtiMain

In ProCall, the value can also be stored in the profiles of the UCServer user administration.
