Here's the setup. PRO II. Ans mach on slt adapter. Btns 1-8 are the co lines - no ring (shared lines). Btn 9 is sie for main phone - delay ring in 4-37. When I call ans mach directly it answers. When I call main phone, no answer. Checked my programming 5 times (identical programming on another ansmach in office with no trouble). I cannot do cfbna because there are sie keys on other phones for the main phone; ansmach set to answer after 4 rings via switch. The kicker....this used to work, and I have reset the system.
