In my PBX setup, I would like that all unused DNs are sent to the NIT number defined in LD15. I have no console defined. So night mode is always active. I've defined a dummy queue 7992 (ncfw Meridian Mail). In MMail, 7992 is defined as announcment. When I'm calling from outside to an unknown number, I receive from MMail "your session cannot continue at this time, please try again later". Any idea what is wrong?
