Our NEC Dterm80 has the "record" button lit and we cannot pickup the voicemails or send VM to other extensions. Can you help?

Press the "Speaker" button and enter 728 on the key pad. Then enter the correct time in 24 hour format. For example at 2.56 p.m. type 1456. Then press speaker again and you're done

For the green light, you can turn it off from DSS. On the bottom left hand side of DSS, it is a message button. You can press the button and then your extension button. The green light will go away from the DSS and on your phone. I hope this helps.

OK, I got this from somewhere else. But anyways, pick up the phone and dial 700, then dial the extension number, then finally you can punch in the name like you would doing a text message. When you're done, hit Hold, hang up, and hit Speaker twice.
