[Freeswitch-users] Execute app in sync mode when using event sockets

[Michael Collins]

Are you using the Java ESL library? If so it should have what you need to
do sync vs. async on sending execute commands to the event socket. If you
are not using ESL I would advise you to do so since it has solved this
problem (and others) already.
