I want to trace function calls in a kamailio module, e.g. ims_isc module. I installed kamailio-dbg package and started the kamailio with gdb: `gdb kamailio` I also set break point on target function, but it seems gdb doesn't stop on that break point.

How should I start gdb and set break points? it seems gdb couldn't handle kamailio child processes that forked in start.

Regards,

Ali
