Methods and systems for controlling network gatekeeper message processing
include overload control routines executed by a network gatekeeper to prevent the
network gatekeeper from crashing during overload conditions. The overload control
routines are executed in a predetermined order so that messages relating to calls
in progress are preferentially processed over messages relating to newly originating
calls. Fault detection routines detect protocol stack and application level faults
of a network gatekeeper.
