You will need the CVS version. Or you can use the Media Proxy - which has something similar and works with 0.8.12.

I didn't mention it but I have version 0.8.12 from source (not RPM).
I've tried searching all the modules source code and I can't find any
references to nat_uac_test. Is this function in the nathelper module or in
something else?

probably you use an old ser version (rpm?). Get the latest stable from
cvs and build ser yourself. Then you have the nathelper module with all
features which were introduced after the first 0.8.12 release.
