In a network that supports communications between client devices and at least one meeting server, a meeting request that includes one or more meeting constraints to be satisfied is monitored prior to scheduling or initiating a meeting between a plurality of meeting participants associated with respective client devices. At least one meeting constraint includes a location constraint that identifies a location for a client device associated with a meeting participant prior to scheduling or initiating the meeting. In response to each meeting constraint being satisfied, including the at least one location constraint, the meeting is automatically scheduled or initiated for the participants via the meeting server.
