[Freeswitch-users] ESL Bridge

Wed May 18 10:07:41 MSD 2011

I've been unsuccessful in trying to get use of SetAsyncExecute and
SetEventLock to temporary switch to sync, while in outbound async full
mode. System behaves as is. and finally I've decided to stick with
async paradigm, and store events in spool, and than analyse regardless
of the order. Maybe I was doing something wrong, but more
test/analysis definitely required there...
