A method and system for managing communications based on originating location. A network entity maintains or has access to a log of the originating locations of calls placed to a given destination. In turn, when another call is placed to the given destination, the network entity refers to the log to determine whether more than a threshold number of calls have been placed to that destination in the past predetermined time period. If so, then the network entity causes the call to be routed to an alternate destination for alternate handling. The invention is particularly useful to help reduce the possibility of overloading emergency call centers when many mobile callers call from a common location to report an emergency.
