Lync / Skype for Business
The architecture of UC Connector integration with Lync or Skype for Business does not change with the Microsoft versions; however, it changes depending on the configuration of the Microsoft platform.
In all cases, UC Connector links the Genesys environment and the Microsoft solution in the enterprise. For presence, communication between UC Connector and Lync is through MS-PRES. For a complete description of MS-PRES see
The UC Connector does not play an active role in instant messaging communication with Lync / Skype for Business. IM sessions are handled between Lync / Skype for Business and SIP Server exclusively, over SIP.
However, for integration with the Microsoft Lync / Skype for Business Client, the UC Connector is able to send a special IM message that starts a context-sensitive IM conversation in the Lync or Skype for Business client. The special IM prompts the Lync or Skype for Business client to open the conversation extension window, in which a browser window points to the UC Connector GUI. This is done only if the UC Connector GUI is not already open on the target user’s desktop.
