As far as I know the ISDN protocol allows to send a CONNECT message immediatly after receiving a SETUP, so I'm wondering why I cannot call the "ftdm_channel_call_answer(channel)" in a "RING" state. Is this a problem of my software or the normal behaviour of the FreeTDM library? </div><div><br></div><div>Thanks a lot for any
