Hi.

The Volume function of that phone is controlled by the up down vol button on the phone. the only time it does anything is when that function is being used. ie. when you have the handset in hand the vol buttons control the handset volume, while the phone is ringing the buttons control the ringer volume etc.

Seems to be a known issue. The normal way is to disconnect the main control box unit. There is a video in the link https://www.google.com/search?q=wo+lines+stuck+on+a+Norstar+phone ..

Check handset cords

Set System Time 1-Feature **TIME 2-Password: BASIC 3-Change time as prompted in the display

You are probably inadvertantly did a busy station signal to sta 24 and are still queued up to it. Call 24 AND have them ANSWER to clear it. You may have to do it multiple time as most systems will allow 8 stations in the queue

Does it light up? Does the speakerphone work? Have you swapped the cords and handsets?

I'm have trouble seeing through the internet and do not know what make or model you are referring to? Have you tried being ON THE HANDSET and then pressing the handsfree/speakerphone key?

Make sure its plugged in right.

Try swapping them with phones that are working. Make sure they are not in DND as well.

Have you contacted Norstar?
