An enterprise network is provided that includes a plurality of internal terminalscorresponding to a plurality of subscribers and a network reconfiguration agentoperable to (a) determine that at least one of a requested connection to a first terminal-associated with a subscriber and a connected communication with the first terminal-will have and/or has an undesirable grade of service and (b) in response thereto, perform at least one of the following operations: (i) direct the requested connection or connected communication to a second terminalassociated with the subscriber; and (ii) change the communication path for the requested connection or connected communication from a first communication path comprising a first networkbut not a second networkto a second communication path comprising the second networkbut not the first network

Disaster recovery via alternative terminals and partitioned networks

In one configuration, the present invention is directed to an enterprise network that includes geographically dislocated first and second network regionsandcommunicating with one another through first and second networksandand respectively comprising first and second gatewaysandand first and second groupings of trunks. A common electronic address is associated with the second grouping of trunks. A media serveris positioned in the first network regionthat includes an inter-gateway routing agent. The first network region transmits, as part of the establishment of a real-time or near real-time communication between first and second subscribers respectively in the first and second network regions, the common address to the second gateway. After the outgoing communication is answered by the second gateway, the first network region transmits in band to the second gatewaya user identifier associated with the second subscriber and/or a phantom user. The user identifier is used to establish the communication with the second subscriber.

In-band call association signaling for a single number destination

A system for call conferencing a plurality of participants is provided that includes (a) an input operable to receive, from a conference call participant A-E, at least one of (i) a selective listening request and (ii) a request to remove selective listening, wherein the communication devices-of the conference call participants A-E are connected to a plurality of gateways; and (b) a conference configuration agentoperable, in response thereto and during the conference call, to change from a first conference topology to a second conference topology, wherein the first and second conference topologies have a different number of inter-gateway connections.

In one configuration, an enterprise network is provided that includes geographically dislocated first and second network regionsandthe first and second network regions being in communication with one another through first and second networksandand respectively comprising first and second gatewaysandand first and second groupings of links connected to the second networkA common electronic address is associated with the second grouping of links. In response to a request from a first subscriber to initiate a communication session with a second subscriber in the other network region, a media serverdetermines that the first networkis currently incapable of supporting the bearer channel for the session. In response, the first gatewaytransmits the common electronic address to the second gatewayAfter the common electronic address is received by the second gatewaythe first gatewaytransmits in band to the second gatewayan identifier that is used to establish the communication session.

Alternate routing of media connections within a single communications system across public or private network facilities

In an integrated voice and multimedia communications system (FIG.,), an end-user is given explicit control over which audio access mechanism he wishes to use regardless of whether a call is a multimedia or a voice call. The end-user's voice terminal (,) is equipped with a PC-Audio control button (,). When the user originates or receives a call, a multimedia PBX (,) automatically connects audio to the voice terminal's handset (,) regardless of whether the call is a multimedia or a voice call. If the user then presses the PC-Audio button, the PBX transfers audio to the audio subsystem (,) of the multimedia terminal (,), an LED (,) associated with the button is lit, and the user may cradle the handset without disconnecting the call. If the handset is subsequently lifted, audio is reconnected to the handset and the LED is extinguished. If the button is pressed while its LED is lit, the call is disconnected. If the voice terminal is equipped with a speakerphone (,), interaction thereof with the PC-Audio button mimics a telephone with an integrated speakerphone that is supplemented with an external speakerphone connection.

A switching system (100) inserts H.320 multi-media protocol-terminating resources (156) into an existing call dynamically, only when the resources are needed, and also removes the resources from an ongoing call dynamically, when the resources are no longer needed, whereby the switching system can provide call features such as hold, conference, disconnect, drop, and transfer, to an H.320 multi-media call and can do so spontaneously, whenever desired during the call, without tying up the resources for the duration of the call even when they are not needed. To extend these capabilities to both single-channel and multi-channel multi-media ISDN BRI calls, the switching system associates a plurality of calls that constitute the individual channels of a multi-channel call and treats the associated calls identically and in unison for purposes of insertion and removal of resources and the providing of features.
