The Unified Communications Managed API version 1.0 Signaling layer exposes an extensive collection of classes, interfaces, and enumeration types. The API can be divided into the following feature-based categories.
| API Category | API | Description |
|---|---|---|
|
Endpoint |
An endpoint can be thought of as encapsulating a user profile involved in real-time communications. These classes thus provide a local context, including the security context of a user. |
|
|
Connection |
RealTimeServerConnectionManager |
This category of classes is used to manage connections for endpoints. |
|
Session |
This category of classes is used to encapsulate the signaling session, as well as message-related data, including the headers, body, and participants. |
|
|
Media Description and Negotiation |
This category of classes encapsulates the features for parsing the content of SIP messages and performing media negotiation. The Sdp class is used for parsing SDP<,> messages arriving as the payload of SIP packets. |
|
|
Publication and Subscription |
This category of classes is used in publishing and subscribing data. |
