You can create a 3-way conference any time, it's easy! With a call on the line, press a LINE key, call the third party, and press the Conference and LINE buttons, and all three of you are connected.
You can even do 3-way conference calls from most standard analog phones.
Although this conference feature is limited to 3 callers, you can "cheat" a little by adding in a co-worker who then adds in another caller.
For larger conference calls, use our Conference Center, which has no limit on the number of callers.
