            sl_send_reply("404","Not here");
        }
        exit;
    }
....

I try with {"topoh_required", (cmd_function)m_topoh, 1, fixup_uint_null , ANY_ROUTE}

no change ! :( always the same error

Thank you Marius,

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

and now I have another problem, When it starts, Kamailio says :

-----------------------------------------------------------------------------------------------

Not starting kamailio: invalid configuration file!

0(19622) : <core> [cfg.y:3329]: parse error in config file /usr/local/etc/kamailio/kamailio.cfg, line 328, column 19: Command cannot be used in the block

ERROR: bad config file (1 errors)
----------------------------------------------------------------------------------------------------

Hello,
In what block are you using the function ? As I check the module exports you kind of have everything there . Can you provide a snippet of your cfg that shows how the function is used along with the block information (failure_route, reply_route)

I search on google and i find this:

http://www.mail-archive.com/[email protected]/msg07610.html

Is it the same problem for topoh as in this mail with tm ?

Not quite. The tm "problem" is a design decision that somehow manifests the same why as your problem

I suggest that you add the cmd with this line

{"topoh_required", (cmd_function)m_topoh, 1, fixup_uint_null , ANY_ROUTE}

so you can call the function from any cfg block(it your resposability to ensure that it makes sense to do it so)

thank you

You're welcome
Marius

ps: I 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
00008c70 t m_topoh
