The three functions discussed in this chapter belong to a new Audio Input (AI) API, which is an additional feature supported on DM3 boards equipped with an audio input jack, such as the DI Series boards. The AI API is used to provide music or other information on-hold. For example, your application could arrange for music to be played to any phone connected to a supported board by listening to the timeslot number provided by the ai_getxmitslot( ) function. See the API function descriptions and associated sample code for additional information on this process. For information on finding out how many AI devices are available, see 10.2. Determining the Number of AI Devices in a System.
These functions are not currently documented elsewhere, but the information is detailed here for your convenience:
