[Freeswitch-users] Event-lock, sync/async on outbound ESL and execute() tagging question

[Dmitry Sytchev]

I understand this. I use outbound async full ESL mode, launching socket app
from dialplan, because in sync mode I have some problems with bridge app and
I need to catch parent channel hangup and server disconnection.

I written wrapper around ESL.pm to implement executeSync which waits for
CHANNEL_EXECUTE_COMPLETE while in async mode, works for now.
But of course it is not the best way, because of possible error when
'execute' is used before my 'executeSync' by mistake and without proper
event handling so that CHANNEL_EXECUTE_COMPLETE from previous app is catched
by my wrapper and it returns prematurely. This is why I want to have some
tag I can mark execute call to filter its events later... Maybe there is
better way?
