[Freeswitch-dev] How to read RTP package/data?

Hi there, I am new to FreeSwitch, and I have a question to ask. If I want to read the RTP package (data from a person picking up a phone and speak or an answer machine) in C++ or C#, what function should I call to get it?  Currently I can make a call to a phone and play an audio. Thanks in advance.  Frankie ____________________________________________________________________________________ Never miss an email again! Yahoo!
