Hi there,

 

I would like to dial a phone number, and read the RTP package back when connected so that we can analyze the data; (to determine when we should play an audio at the right time--human or answer machine.)

 

We found a code for IVR test (http://docs.freeswitch.org/switch__ivr_8c-source.html) Function name: switch_ivr_sound_test

 

We would like to do the same but with C# code, but we encountered a problem when calling the function "freeswitch.switch_core_session_read_frame(  ) "

 

< in swig.cs

 

switch_core_session_read_frame(SWIGTYPE_p_switch_core_session session, SWIGTYPE_p_p_switch_frame frame, uint flags, int stream_id)   >

 

where the second parameter--frame is a pointer to pointer of switch_frame type and in C# code, it is having a difficulty passing an object to the C++ side and keep the pointer place holder before going deeper into the C code (switch_core_io.c)

 

1) So is there any way I can call this function in C#?

2) Is there another function or routine that you can suggest me to for reading RTP package?

Thanks,

 

Frank
