I would like to trigger playback into a channel, and I'd like to do that using a networked request that indicates the filename. Is there a better way to do it than the following? I'm considering using ESL (in inbound mode). I already have a large dialplan, and rather than reimplement all of it as ESL commands, I thought I could add the uuid_park application into the dialplan at the spot where the inbound channel(s) should be fully configured and active. There would be a separate server running an ESL client, and once it gets an ESL CHANNEL_ANSWER event it would be able to invoke playback until it receives a CHANNEL_DESTROY event. I considered other programmatic ways of doing playback such as mod_python, but they don't address the networked requirement.
