You can directly initiate the callback from Microsoft Outlook via SAPphone: For example, you can select Call back directly from the context menu (ríght mouse button). In the form itself you can still change the telephone number before (double click on the work item). The telephone system itself is however controlled by SAPphone so you must be in Online Mode.

The form is called Mpphone.fdm (fdm = form descriptor message) and is located in the MAPI subdirectory of the presentation CD (path Gui\Windows\Win32\Sapgui\Mapi). You install it in the personal forms library in the same way as file Mpform.cfg (see Creating Profiles, step i. in the manual configuration).

As the callback involves a specific work item, you must have made SAP MAPI "workflow-compatible". For further information see Processing Work Items in the MAPI Client.

You require a corresponding telephone system and must have configured SAPphone. For further information see SAPphone.
