Matt!Thank you so much for such a deep explanation.But You still did not reveal your plans about accessing Asterisk builtin apps :-)Once more example - a pause before playback.In ARI you cannot use python time.sleep(1) as it blocks the whole async event loop.How to tell a channel to wait?
Since you mention an async event loop, I'm going to assume you are using twisted - although ari-py does not use that. If, however, you are using twisted, I would just do something like the following:
def play_something(chan):
chan.play(media='sound:tt-monkeys')
# Assume chan is a reference to my channel
reactor.callLater(1, play_something, chan)
If you aren't using twisted, you could use the threading.Timer module [1] to schedule a callback in a similar manner.
Or you can make Asterisk perform the pause:
chan.play(media='sound:silence/1')
Since ARI queues up sounds, that will automatically either (a) play 1 second of silence immediately, or (b) play 1 second of silence whenever the current media operation finishes.
