We cant hear the phone ring in our office now!

Have a coworker call your extension to see if DND is on, they will go straight to voicemail or get a fast busy. Speaker 42 may be the default cancel DND code, depending on your system and whether the codes were changed. Anyway, ringing is set up in system programming. If someone calls your extension it will likely ring, but outside calls have to be assigned to ring in system programming. Usually need a tech to do the programming since it gets complicated very quickly.

Dterm 80 works on several systems, would be helpful if you mention what system you have. Programming lines directly onto a phone is done in system programming, not really something you can do yourself. If your IT person has the programming software, great. Very rare someone on site is tasked with knowing the phone system at that level, because it gets deep quick, and your working on the whole thing, not just one phone.

Several phone vendors post user manuals on-line. Dterm 80 is a phone that works on about 10 NEC phone systems. Find out which system you have; Pro II, Elite, IPK, IPK II, SV8100, 8300, 8500, and so on, then Google your system+user manual+PDF.

Ringing is assigned in system programming, so if your phone doesn't ring you can't change that unless you have person on site who works on the system at that level. Some places use the night mode feature to make certain phones ring in day mode, and others to ring in night mode. Not very likely but sometimes the mode gets switched at places who don't realize they have another mode, suddenly only 2 phones ring instead of ...5. Feature,80,Feature, is the code to switch back and forth on a Pro II, an Elite, and an IPK system. This would be done at the reception phone. These phones also work on several other systems so don't know if this works for you. Or maybe you set Do Not Disturb, which would keep your ringer off.

Thank - you but I have found a company from whom I can buy a NEC cordless phone. Have a good day.

I have a DtermSeries E and the second line blinks but does not rings.

You will need a professional installer to do this for you.
Cross conecting and proper grounding required for any installations.
