We are not getting a courtesy beep or ring when I transfer calls to 10 out of 12 lines in my office. Is there a way to fix this problem w/out having to call a tech top come out?
Also, I've tried to hook up a headset ( 01-03 H9A)with a modular headset ampliphier by plantronics (M12). My phone is a Inert-Tel (Model: Executive Digital Terminal) (Part Number: 550.4500) but I can't seem to get it working. Can yo uhelp me with this?
