Not really.  The audio stream uses the RTP payload format 
"audio/G726-32", which is G.726 audio encoded at a sampling frequency 
of 8000 Hz, with 4 bits-per-sample.  Note that these 4-bit samples 
are packed into bytes in 'little endian' order.  See RFC 3551, 
section 4.5.4.  The resulting file contains (exactly) the contents of 
the RTP stream, and so is in the same format.

I'm sorry, I can't help you here.  I'm not an expert on "ffmpeg" (or 
any other decoder software).
