AGI is an interface. It consists of reading the AGI environment from STDIN and then, writing requests on STDOUT and reading the response from STDIN.<br>

Right! I did read that, the problem is how do I do this in bash?? I tried read the result in and just post a Noop kind of a thing just to tell that I read something, but it didn't help. I also explicitly did that in the perl script, but doesn't work. It only works in PHP.<br>

Bash would probably be my last choice of language to write an AGI with.<br>
<br>
Personally, I use C because it is my sharpest tool and because you can execute hundreds of AGIs written in C in the time it takes to load the Perl or PHP interpreter and parse your script.<br>
<br>
I suspect that the problems you are experiencing with Perl may have something to do with flushing STDOUT or reading the complete response from STDIN.<br>
<br>
I strongly suggest using an existing library for the language of your choice.<div><div></div><div class="h5"><br><font class="Apple-style-span" face="'trebuchet ms', sans-serif" color="#000099"><br></font></div></div>

Not planning to write an AGI script in bash actually...it will be written in C# running on a remote system. I was just doing a quick PoC to figure out how would I use the stream file function to actually read audio files over the network and even though I used to teach Perl 10+ yrs ago, I don't do much scripting/coding for a long time, so the brain doesn't think like a coder anymore. Just needed to try various tricks w.r.t to how can I dynamically bring over audio files from another server, convert them to the codec of my channel and then play/store them locally (cache if you will) but wanted to learn the right way to do it with a local file first before I tried something fancier. Guess I'll continue playing with the php script that worked and once I figure the process out, will give it to the C# dev to implement. Can't believe I wasted more than 2-3 hrs on this :(</font></div>

How / what is the best way to stream audio files (not MOH/Internet Radio/TV and what not) inside a dialplan using AGI without comprising performance/adding latency too much. no examples of shout/ICE I could find that show how to do that simply by allowing me to run a web server remotely and use a shoutcast module to play the audio right into the channel</font></div>
