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.

Splitting incoming calls between the signaling and collaboration layers

Posted: June 7th, 2013 | Author: | Filed under: UCMA 4.0 | Tags: | No Comments »

If you want your UCMA application to handle some (but not all) incoming messages at the SIP level, it’s possible to split requests between the “signaling” and “collaboration” layers of UCMA. You can do this by using the InnerEndpoint property on your UserEndpoint or ApplicationEndpoint object. This property gives you access to an instance of RealTimeEndpoint, the alter ego of UserEndpoint or ApplicationEndpoint from the signaling layer. By subscribing to an event on this RealTimeEndpoint object, you can give your application an opportunity to handle calls on the signaling layer.

Accessing the inner endpoint

Although the title sounds very philosophical, I’m not going to talk in this post about an inward journey of discovery for your application endpoints. Instead, I want to talk about a way to access some parts of the signaling layer – the lower-level part of UCMA that allows you to work directly with SIP messages – from the collaboration layer, where most UCMA development takes place.

Manipulating SIP headers with UCMA

Posted: October 7th, 2011 | Author: | Filed under: UCMA 2.0, UCMA 3.0 | Tags: , | 5 Comments »

For the most part, UCMA keeps Lync operations at a high level, and allows you to ignore the details of the SIP messages that are going back and forth. At times, however, you may need to look at the actual SIP message that a UCMA application is sending or receiving, or add a specific header to an outgoing message. This post shows how to do both of these things. Continue reading “Manipulating SIP headers with UCMA” »
