Component APIs

In addition to the primary phone XSI API, two additional component APIs are available:

•Application Management API, page 4-1

•RTP Streaming API, page 4-1

Application Management API

To address the limited application management, the Application Management API provides a smoother hand-off between the call mode and the application mode. The Application API consists of two primary components:

•Application URI—see the “Application” section on page 5-18

•Application Event Handlers—see the “Application Event Handlers” section on page 3-22

Note Support for the Application Management API requires an updated XML Parser (see “Updated XML Parser and Schema Enforcement” section on page B-1for details).

RTP Streaming API

This XML-based RTP Streaming API allows applications to initiate and observe RTP audio streams. It extends capabilities beyond the legacy RTP streaming URIs by providing support for stream start/stop event listeners and the ability to specify other extended stream attributes, such as codec type.

Note Support for the RTP Streaming API requires an updated XML Parser (see “Updated XML Parser and Schema Enforcement” section on page B-1for details).

The event handlers typically use the standard Notification framework (see “Notify” section on page 5-16), but they can also invoke most other URIs, with the exception of HTTP URLs.
