“Will the CM18045 show an indicator light (on the handset) when a line is in use by the CM18445 (main console)? If not, how does the person using the CM18045 (handset) know when a line is in use?”

• The line button of the CM18045 will light up indicating which line is in use on a different extension. It will also show an icon on the screen as to which Line and which Extension is using the line. Thank you for your interest - Vtech Support
