Your issue depends on the software version of the ECS. If it's 4.x or higher, there's a setting in ACD - Group Data- Xfer Calls NT and Xfer Calls Day. Make sure the Xfer Calls NT points to the Night Call Sequence table. This will handle calls transferred by any PBX extension including automated attendant. In versions prior to 4.x, transferred calls can only be directed to one Call Sequence table (normally the day table).
