Hello Jerome

Have you installed your module? Can you double check that the module 
loaded from the config is the same as your patched one? You can also use 
full paths to load module, so I suggest to do a

loadmodule "/home/path/to/kamailio/modules/topoh/topoh.so"

Also check if the m_topoh function is compiled by looking at the symbol 
table in the topoh.so file

nm -a topoh.so | grep m_topoh should work just fine.

As I look thru your code, I can't see any possible errors. I will look 
more closely if with these suggestions don't work

Cheers
Marius
