Summary:An intermediate device is described that reduces the number of signaling registration requests and responses flowing across a network. For example, a load reducing device intercepts the registration requests, filters a portion of the requests, and outputs autonomous response for each filtered registration request. The load reducing device forwards an unfiltered portion of the registration requests sufficient to maintain registration of the requesting device. The autonomous responses keep a logical pinhole in a firewall in an open state so that the registering device behind the firewall can receive session initiation invitations. At the same time, filtering the portion of the requests reduces the number of requests and responses that traverse any intermediate networks between the load reducing device and an intended recipient of the request.
