Microsoft Lync and Skype for Business have a rich set of .NET APIs which make it easy to extend the platform and integrate it with other applications. This blog helps explain how to use those APIs.

UCMA does a very good job of putting a layer of abstraction over the extensive SIP signaling that goes on at a lower level during both of these operations, which is a good thing overall, since it frees up developers to focus on solving business problems using the API. However, at times it is useful to know things like the underlying difference between a conference invitation and an MCU dial-out in order to solve complex technical questions.
