your probably getting messages or sometimes on my phone it has a minute reminder and the beeping sound comes on every minute.

You should be able to go into message settings and turn the reminder beep off.You would find this under Message Settings, General, Message Alert.

It is hard to tell if this conference phone is installed on a PBX or not? "At meetings" tends to make me believe that it is. Beeping can come from a few sources. If a call is being recorded it is necessary to provide a beep tone so that the parties on the line know that they are being recorded. This is a FCC requirement. You can ask the other party if they are recording the call. Beeping can come from call waiting. It is recommended to turn call waiting off unless you are bridging incoming calls. If a call is on hold you will get a beeping tone. You can check by pressing the flash button and see if there is a second call. If so hangup and your original call should return normally.
