Hi,
Thank you.
Hi,You are better off using mod_freetdm.c as the reference, the sample/test applications may be outdated.
ftdm_channel_t is an opaque type to API users. I don't remember what your exact question was. You should not use fchan.caller_data, you always get a copy of caller_data when you need it, the fact that is internally attached to the fchan pointer is not something you should rely on (and that's why is in a private header).
