I have a reception phone that when on nite mode my auto attendant picks up, and then transfers to the reception phone to make sure that phone gets the blinking light for a message. During the day when she just walks away from her desk, I want it to do the same thing, but I don't want her to have to put it on night mode. I also want to know how to change the number of rings that happen before other extensions hit voicemail. I have an F420 voicemail or phones system model. Not sure which is which. Inherited system from another company.
