You can create two types of conference calls with your BlackBerry® device. If your organisation or a conferencing service has provided you with a conference call bridge number, you can create conference call meetings in the calendar on your device or computer. Conference call meetings allow participants who have a BlackBerry device to enter the conference call meeting with a one-touch Join Now option, if this feature is supported on their device, so that they do not have to dial the conference call bridge number and access codes. If you do not have a conference call bridge number, you can create a conference call by calling other contacts and joining the calls together.
