AT&T corded 2-line speakerphone model 993 doesn't show area code

The poster was asking about how to turn off he "new Call" lights for both lines. I don't have voicemail set up through phone company, so there aren't any "new Calls," so these don't flash, but stay solid red. Is there any way to turn off these lights?

Also, I have my Line 2 set as default line. Usually, Line 1 has no lights lit up unless someone is on that line on another phone instrument. Recently, however, the red light (indicating that line 1 is in use) either flickers on and off or even stays solid -- when line is NOT in use. Also, does anyone know how to turn off the red lights which indicate new call on each line? I can't find any support on this. Do you have any ideas? Thanx

New call light is just that, you've had calls that weren't answered and are stored in the call history to clear them you'll need to clear call history. You could also turn off the phone company voicemail since you don't use it, page 24 and 25 of the manual. New call, call history pages 52 and 53. Manual found here. If you'll note on the original topic of over a year ago that you commented on, it was stated that I didn't check the manual, as the OP said they had the manual.

Thank you so much. That cleared the New Call lights. (I don't use voicemail from phone company.)

However, do you know anything about my other question:

I have my Line 2 set as default line. Usually, Line 1 has no lights lit up unless someone is on that line on another phone instrument. Recently, however, the red light (indicating that line 1 is in use) either flickers on and off or even stays solid -- when line is NOT in use. The phone cord is not impinged.

Thank you.

What type service do you have on line 1? Digital like U-verse, traditional landline (POTS), Wireless home phone, or something else, like magic jack?

both are hard-wired Frontier Fios digital phone lines.
