I set up a hunting group that contains couple of extensions. The last extension in the hunt list has an Unity voice mail box. The hunting group runs OK (top down, try next number based on the hunting group sequence). Every phone rings. However, the caller will hear a busy tone instead of greetings from Unity after he reaches the end of the hunting list extensions. The voice mail at that extension works OK if it is a normal extension or external call. Did I miss some parameters? Is it a limitation on hunting group? I need some guidance from expert in this area.
