[Freeswitch-users] question about outbound socket async

[Seven Du]

For sure I'm using a recent git.

I test with nc and didn't found a problem, but in erlang it does has
problem I didn't test much so I just sleep some milliseconds after I
sendmsg break that works for now.

Let me tell you what I was trying to do:

an erlang FSM (like outbound event socket) controls a channel and can

playback to channel
listen to DTMF and send to a UDP server
listen to a UDP and break the current playback and play new voice on
new instruction

The problem is that it can get UDP instructions any time and can be
very quick( say, get 2 playback instruction at the same time).

So I want to listen to CHANNEL_EXECUTE to make sure a playback is
actually executing and CHANNEL_EXECUTE_COMPLETE to make sure if it
stopped. And also for the break APP.

The state machine would be complicated if I need to worry about all
the races. It might be better to implement in C but it's actually a
simple program which I think it's overkill for now.

Thanks for your help, a simple sleep works for now. Will worry about this later.
