Here are some steps that should help. I don't think that you can Conference call You can hold a 3-way conversation (conference call) between your handset, an external caller and another internal handset user. During an external call: 1 Press . The external caller is put ?on-hold?. 2 Press or to select name, number or the handset you want to have a conference call with and press or key. The called handset will ring. 3 When the called handset answers, press to start your conference call. 4 Any handset can press at any time to leave the conference call. It looks like you can use the multiple system sets together, but the system is not designed to do what you are asking for. Please repost with any other comments or questions. Please rate this solution through fix-it. Thank you.

Try disconnecting the power from the back of the base. Then press and hold the delete key while reconnecting the power. When power comes back on press play one time. If that does not work, your unit needs to be replaced.
