Hi: We just purchased a KXTD1232 system to use with out KXT7230 phones. I have a small problem I thought maybe you could help me with. My night mode is set automatically and I love it because I don't have to physically set it. My problem is that in the day mode, when I program it to go to VM, 1. the extension where these CO lines supposed to ring does not ring, 2. the VM will pick the call after 2 rings. How can I set it so that in the day mode, when the extensions are busy/NA then the calls will go to VM after, let say 4 or 6 rings? I have set the FWD/DND button on the extension to go the VM but this still does not work.
