I must agree;  I have already in one of my branches replaced most of 
the hard coded 8000 samples per/second assumptions with a variable 
which is per-codec dependent field.  You can check out my 
asterisk-wideband tree from svn to see, though I haven't updated it in 
a while.  I've just about got done with a codec_g722.c though, so I 
should be making more updates to it soon.
