KSU: KX-TD1232-4 (rom P211D00712A) single cabinet
VM: KX-TVA50 (with 2 port DPITS expansion card)

PROBLEM:
I can't get the voicemail answer after delayed ringing (during the night as day rings all staff). I've changed 604 to various settings but nothing seems to get the voicemail to pickup on incoming calls. If I change the lines in 408 (night dil 1:1) to extension 165 it works fine and picks up immediately but we don't want immediate ring. Any ideas?
