Systems, devices, and methods are described for initiating collaboration activities among multiple terminal devices. A central server computer system may receive a trigger event for a collaboration activity at a central server computer system; identify a set of participants in the collaboration activity; identify a current device associated with each of the identified participants; and apply a set of rules to the received trigger event and the identified participants to preemptively establish a bridge for the collaboration activity between each of the identified devices prior to a start of the collaboration activity.
