I am new to Asterisk and am wondering how capable it is out of the box for random IVR capabilities. For example, some uses I may need to support:
capturing DTMF tones and responding accordingly
sending DTMF tones so as to interface with other IVR systems
recording a user’s voice, both short and longer recordings (for a custom messaging system)
full-duplex recording, allowing a user to record their voice while music plays
recognizing vocal input on-the-fly for menu navigation (or to start/stop recording)
Would I be writing a module of some sort to plug in to Asterisk to host, I assume? Which API and what documentation should I be looking at to be prepared to handle this? Finally, I assume Asterisk at least handles handing off the raw input (and streaming in audio to be output), so I wouldn’t need to edit Asterisk’s code itself to achieve the things mentioned above.
