This is problem is screaming "event socket" all over

Yes, but is there any reason YOUR application can't talk to FreeSWITCH over
the event socket?

Again, the event socket lets you have this kind of control.

When you say that the caller calls your IVR application, what exactly does
that mean? Do you do SIP handling in your application? Do NEED to do SIP
handling? You could have the call terminate and FreeSWITCH and let
FreeSWITCH do an outbound event socket connection to your program - at that
point your program has complete control of this call - you can play TTS,
collect digits, transfer caller elsewhere and hangup. You can even create an
outbound call leg to connect to the callee and do all sorts of crazy things.

I recommend you look at the outbound event socket on the wiki. Also, look at
the fs_ivrd program. It's a handy way to organize calls to a socket-based
application.
