Abstract:
1. A system that facilitates call management, comprising: a routing component, which comprises a session initiation protocol (SIP) gateway on which message ports are initially allocated, for receiving a multimedia message via a public switched telephone network (PSTN) interface, the PSTN-originated message destined for an enterprise recipient of an enterprise for termination in an enterprise; a private branch exchange (PBX)/media server to request PSTN message information about the multimedia message from the PSTN interface related to routing of the message; and a session component for: sending a request for PSTN message information of the PSTN to a SIP PBX gateway, the SIP PBX gateway to forward the request to the PSTN, and the session component to receive the PSTN message information from the PSTN via the PBX/media server and, based on the message information, forwarding a bridge request to the routing component with a routing signal including the message information, the routing component operable to forward the routing signal to the PSTN interface to trigger bridging of the multimedia message in the PSTN rather than through the enterprise, by sending a routing signal from the PSTN interface to the PSTN to initiate a two B-channel transfer (TBCT) in the PSTN bridging the message in the PSTN, wherein the allocated message ports are subsequently freed up for reallocation based on routing of the message outside the enterprise.
