James -
   It would seem that codecs should be specified in some contexts 
within the [iax, sip, etc.].conf files, or they should have a config 
file of their own where they are "named" such that other config files 
can simply refer to the name of the desired codec.  This would 
involve a lot of work, but would make codecs fairly extensible to 
multiple channels.

Here's an ugly start at it.  Not too much thought has been put into 
making this an exact example:


-- start of hypothetical file
; codec.conf
;
[default]
bitrate=default
vad=off
khzrate=default

[speex-15]
basecodec=speex
bitrate=15
vad=on
vbr=on
khzrate=8

[ilbc]
basecodec=ilbc.so


[g729]
basecodec=g729
vad=off
bitrate=default

[g711u]
basecodec=g711u
bitrate=default
