Just to reignite this whole thread. We've had great success with Stasis

so far. We have implemented a (imho better) AMD using TALK_DETECT and

the ARI events. When using this, it seems like calling /play multiple

times will just queue up the audio files. This is probably the best use

case and most common implementation. However, if half-way through our

third audio file we realize that we've been speaking to a machine this

whole time and we want to start for the beginning - we thought we would

use DELETE /playbacks/{playbackId}. If we do that, however, and then

subsequently try to play audio on the channel (even though the call is

still connected and in the Stasis app) we get a Channel not found. Is

this the intended use or even a good use?

Stopping a playback, or multiple playbacks in sequence, like that

shouldn't result in you being unable to do things on the channel. Do you

have the output of what you are invoking and the log from Asterisk? It

may be a bug.

This happens after we do a DELETE on /playbacks/{playbackId} (which I use the channel ID - I am going to test with a different, fixed ID)
