Re: [Asterisk-java-users] How can i use this library to make a call and run an audio file on it

[Brandon H. <bh...@ta...>]

Hey Adriano,

Yes, the code I shared is showing how to receive a call and respond with
audio.

I have a scenario where we allow users to initiate a call to themselves (by
pressing a button in a Web App) and when they pick up the call, we stream a
couple of audio files (one after the other) to give them instructions for
the system they are using. In our scenario though, we are just initiating
the call through the use of Call Files (
https://wiki.asterisk.org/wiki/display/AST/Asterisk+Call+Files). When the
user picks up, they just drop into the context specified in the Call File
which directs them to our Asterisk Java AgiScript. In this case, I still
use `getData` on the `AgiChannel` to stream the files when I need DTMF,
otherwise I just use the `exec` method on the AgiChannel to use the
Playback application within Asterisk.

If you are going to originate the Call in some other way, I won't be of
much help at the moment as I have not worked with the Asterisk Manager
Interface, (
https://wiki.asterisk.org/wiki/display/AST/The+Asterisk+Manager+TCP+IP+API)
yet. Asterisk Java does also support the Manager Interface so you might
find something that more closely resembles what you are looking to do at
http://asterisk-java.org .
