[Freeswitch-users] async ESL Events question

[royj at yandex.ru]

Hi, all.

There is some unclear for me about ESL async outbound mode.
I use node.js http://shimaore.github.io/esl/ 
With this simple script https://pastebin.freeswitch.org/24500 I see that sometime events, namelly 'CHANNEL_HANGUP_COMPLETE' and 'CHANNEL_EXECUTE_COMPLETE', not arrive thru socket from FreeSWITCH. How to explain this?

FreeSWITCH dialplan https://pastebin.freeswitch.org/24501
ngrep on socket https://pastebin.freeswitch.org/24502 with two calls. There is no sense about number of calls and their order, no any system for me. Only if bridge failed (BUSY) events always arrive.

Thanks for any suggestion.
