Abstract
The invention discloses combined conferencing and calling, and switchable calling for such combined conferencing and calling. In one embodiment, a system has at least a first and a second node. The second node initiates a conference and a call with the first node. To a user at each of the nodes, initiation of the call appears imperceptible as separate from initiation of the conference. In another embodiment, a system has a conference including at least a first, a second, and a third node. The first node has an initial call with the second node. The first node is able to seamlessly switch the call to the third node, without affecting the conference.
