Hey Adriano,
I was looking for a way to send audio through the Manager Interface and I
found this in the FAQ for Asterisk Java.
Currently, there is no support for sending media or files across the

So you will need to play the audio through either regular dialplan code in
*extensions.conf* or by using Agi and Asterisk Java together. Since you are
specifying the context as "from-internal" you can call out to Agi from
within that context and use the code I shared earlier in this thread.
Thanks,
Brandon
