Turn off ringer for conference room

I would like to know if anyone knows how to turn off the ringer for a phone in an office? We have my main receptionist phone which rings and all of the other phones in the offices and the conference rooms just have a red flashing light when a phone call is coming in. One of these phones rings and I need to change it so that it just shows the flashing light.
I am super frustrated... anyone have any ideas?

    We have moved some of our phones in the office. I have the opposite problem. They have one line set to ring, but I want ALL the lines to ring. How do I set that up.

    As for the problem on turning the ringer off; just push the DND button next to the voice mail button and it will silence that phone when people are in your conference room

While the phone is ringing hit the down arrow key on it and the volume will lower. Only if it is an ipk or elite system though. You could enter program mode and remove ringing for that port in MB 4-01

Your Handset has been programmed i guess by mistake to be in the same ring group as the main receptionist for C0-01 . Use Google for programming manual to make changes.

No, that was a drawback of the 44xx series phones. You should use a Polycom conference phone for a conference phone.
