I have this client who puts their system in Night mode. At some point, it seems, someone actually will pick up a ringing line when the system is in Night Mode, and they claim it reverts to Day mode.
Is this 'normal' they want to know, and is there a way to make the system stay in night mode until they press the button to take it out of night mode.

(What they're describing is what I would want a system to do, but someone doesn't like it, so I'm investigating for them). I cannot find any mention of auto day mode in the documentation.

Thanks,
Talbot
