I have a customer that has an ADIX system with (I believe) an IX-4VML card installed. The system goes to the auto-attendant without issue when the system is in night mode (incoming calls are programmed to DIL to group 47 in night mode), but will not go to the AA in day mode (system is setup to DIL top group 0 in day mode with group 47 setup as the delayed hunt group).

The odd thing about it is that if I connect to the voicemail card using the VMI editor and view the status while making an incoming call when the system is in day mode the card shows that the AA *is* answering after the delayed ring timer expires (I see it playing the outgoing message for menu 900, attempting to record a message, etc), though I don't hear anything other than ringing on the calling side.

I've compared all of the settings in this system with the settings on a known good system with similar hardware but can't find anything out of the ordinary.

Any thoughts?
