From an NBX Telephone, follow these steps:

 

You can establish a Conference Call with up to four parties, includingyourself. You must be using a telephone on the NBX system to establishthe call. The other three parties can be any combination of internal andexternal parties.

 

1. Dial a call, or receive a call from someone else. Two parties are now on the call.

 

2. While on the call, press the Conference button (or press Feature + 430).The system selects a new line and places the first party on hold.

 

3. Dial a call to an internal or external third party. Wait for the third party to answer the call, and then press the Conference button (or Feature + 430) again. Until you press the Conference button (or Feature + 430) the second time, the second party remains on hold, and you may converse with the third party privately.

 

NOTE: Only the bigger phones have the Conference button.
