g729 is a commercial codec and requires a license to use. You can purchase a license for use with Asterisk. See http://www.voip-info.org/wiki-Asterisk+G.729+licensing
g723 is also a commercial codec but Asterisk does not support it other than in passthru mode. I have not heard of gsmfr. What about Speex? You can compile this for use with Asterisk and most Cisco stuff supports it as I believe it is the protocol preferred by their own voice system.
