[Freeswitch-users] any IVR example in C/C++?

[xl127]

Thanks for the answer, Moises!

My final goal is to let FreeSwitch (FS) to communicate with my external 
applications in Java, C, or Python,
e.g. to send the ASR results from FS to my external applications.

I know I could do it by FS Event Socket but I am a bit worried about the 
performances by using the Event Socket.
So I thought it might be better to use embedded FS in my apps, set the 
speech input callback to point to
the method in my app.

To use embedded FS, it seems to be easier to find the C API e.g.

switch_core_init_and_modload( ..)

so I was thinking about the FS IVR in C/C++.
(I couldn't find the APIs for embedded FS in others of my chosen 
languages: Java, C and Python)

any suggestions for accomplishing the goal?

Thanks,
Xing
