With Windows, there are different technical options for integrating ProCall as a standard application for selected actions. Depending on the depth of the integration, different interfaces are used here.
Microsoft Office/Outlook Integration
For Microsoft Office/Outlook integration for locally installed applications, a ProCall DLL is set as DefaultIMApp via the Windows Registry. Microsoft Office / Outlook uses this DLL to perform actions on contacts or to synchronize presence.
The behavior of the integration depends on the version and variant of the installed Microsoft Office product.
Therefore, please also note our continuing articles under: Dialing from Microsoft Outlook
