You can add another party to a conference without putting your connection to the conference on hold. This means that everyone in the conference hears the call progress and can immediately hear the other party when they answer. Supported on IP Office Release 11.0 and higher.
You can also add a new party using hold if you do not want the existing conference to hear the process.

1.If not already highlighted, press the up or down cursor keys to display and highlight the conference call.
2.Press the Details soft key.
3.Press Add.
4.Enter the number of the party you want to add and press Call. Alternatively, press Dir to select a name from the directory.
5.If the other party does not answer, is not available or does not want to join the conference, press Drop.
