Abstract
A system and method for using a portable information device, such as a personal digital assistant, to establish a conference call on a telephony network. In one embodiment, a user of the portable information device may select communication partners from an address book application located in the portable information device. Communication information related to the communication partners is transmitted across a link from the portable information device to a voice communication device, such as a data network telephone. The data network telephone may then set up the conference call.
