Engagement Call Control Snap-in

See All Content


Engagement Call Control is deployed as a snap-in on the Avaya Breeze Platform. The snap-in provides a set of RESTful Web service APIs for call control operations and voice messaging. The APIs support capabilities similar to those supported by the equivalent Agile Communication Environment (Avaya ACE) SOAP-based Web service APIs.


  • Engagement Call Control enables client applications to have visibility and control of all Communication Manager calls, whether they be from station-to-station, station-to-trunk, or trunk-to-station. The APIs supports call operations such as make call, answer call, drop call and hold call.
  • Engagement Call Control enables client applications to manage voice mails stored on an Avaya Aura Messaging server.
  • The Engagement Call Control SDK includes a sample application that demonstrates how to create client applications that use Engagement Call Control, plus base documentation for its APIs.
