I am setting up a 500V2 with 8.0.18. I will have a PRI and DIDs. I will have a twinning button on the 1616 phones. I want to be able to turn twinning on and off from the mailbox user menu. How do I get to the personal options menu then to more options. I have been searching the KB but have some confusion. Do I set up a module or a start point? Does the FEN come into play?
TIA
