No, the data portion of the ast_frame may be the rtp frame, though.  There's
an additional 'offset' element within the frame that points to the audio data
within whatever structure 'data' points to, and there's additional information
about the audio codec within ast_frame.  The point of all this is to make
ast_frame extremely efficient as a method of carting audio around within
Asterisk.
