No.  The only codecs that you will negotiate will be ulaw, alaw, and
gsm, as specified in your config.  'show codecs' is informational
only.  It indicates nada, nothing, zip, zilch (get the idea?) about
your configuration.  Asterisk will use whatever codec is available
on both sides, followed preferentially by the codec which has the
least cost to translate.  See the 'show translation' matrix.
