I don't know for ISDN, but for analog lines, the option was not available and I had to patch ftdm_io.c to make it work.
I don't know if the same freetdm functions are used with ISDN and libsng.

Hi all,
I've just tried the FreeTDM module with the libsng. It seems that I'm not getting the redirection number. A called to B. B is redirected to C. In the SETUP packet I got "redirection number" as B. But in FreeSwitch, I've not got the "redirection number". I also wanted to know whether the stack ( libsng ), itself not providing the RDNIS or FreeTDM is not updating it?
Please help!
