'features reload' does not load new features

Asterisk 1.6.2.20
FreePBX 2.9.0.7
CentOS 5.6

Added features to features_featuremap_custom.conf as described in this post: http://www.freepbx.org/forum/freepbx/users/n-way-call

Changed the above feature codes to something that was not already in use by FreePBX.

Issue command ‘features reload’, config files are parsed. Issue command ‘features show’ and new features are not listed. Searching for anything about the feature map has proved difficult.

What am I missing?

Thanks.
