I guess you've got this in the [general] section, then?  The codec
list there is a specification of which codecs are allowed, and they
are listed in order of priority.  Thus, with your list, anything that
*can* speak g729 *will* do so.  You can override that, in individual
per-phone sections in the file:

[faxmachine]
disallow=all
allow=ulaw
