Building Advanced Communications Solutions with UCMA 3.0 In this session, you'll learn about some of the new capabilities of the UCMA 3.0 SDK, such as back-to-back, conference services, and application endpoint draining. Hands-On Labs Advanced UCMA 3.0 Development In this lab, you will use advanced features of the UCMA 3.0 SDK to build communications solutions that use Back-to-Back to mask the identity of a caller in a conference, use audio routes to control the flow of audio between participants in a conference, and drain an application endpoint. Videos Building Advanced Communications Solutions with UCMA 3.0 - Back-to-Back Calling In this video, you learn how to use the new Back-to-Back call functionality in UCMA 3.0 to create a back-to-back call between two participants, where the UCMA 3.0 application acts as a SIP signaling proxy between the participants but allows audio to flow directly between them.
