1. A system comprising: at least one processor; and at least one computer-readable storage medium storing instructions executable by the at least one processor to implement: a scheduling application defining at least one calendar appointment entry having a start time and a finish time, a communication management component defining an interruptibility rule separately from the at least one calendar appointment entry, and correlating the interruptibility rule to the at least one calendar appointment entry, and a communication routing component configured to: save, to a network server component, the at least one calendar appointment entry with the correlated interruptibility rule, publish, via the network server component, the at least one calendar appointment entry and the correlated interruptibility rule to at least one participant of the at least one calendar appointment entry, in response to a participant of the at least one participant accepting the published at least one calendar entry: associate the published at least one calendar appointment entry and the correlated interruptibility rule to the participant, and impose, during a period of time associated with a start time and a finish time of the published calendar appointment entry, the correlated interruptibility rule with respect to handling incoming communication for any of the at least one participant that accepted a published calendar appointment entry, and route, according to the correlated interruptibility rule, the incoming communication of the participant that accepted the published calendar appointment entry during the period of time.
