International Classification:

G01R 31/08

US Classification:

370237, 340 223, 370355

Abstract:

In one configuration, an enterprise network is provided that includes geographically dislocated first and second network regions and the first and second network regions being in communication with one another through first and second networks and and respectively comprising first and second gateways and and first and second groupings of links connected to the second network A 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 server determines that the first network is currently incapable of supporting the bearer channel for the session. In response, the first gateway transmits the common electronic address to the second gateway After the common electronic address is received by the second gateway the first gateway transmits in band to the second gateway an identifier that is used to establish the communication session.

International Classification:

H04J 9/00

US Classification:

370237, 340 223

Abstract:

In one configuration, the present invention is directed to an enterprise network that includes geographically dislocated first and second network regions and communicating with one another through first and second networks and and respectively comprising first and second gateways and and first and second groupings of trunks. A common electronic address is associated with the second grouping of trunks. A media server is positioned in the first network region that 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 gateway a 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.

Abstract:

In one configuration, the present invention is directed to an enterprise network that includes geographically dislocated first and second network regions communicating with one another through first and second networks and respectively comprising first and second gateways and first and second groupings of trunks. A media server is positioned in the first network region that includes a routing agent. When a WAN outage occurs, the routing agent, using a dial plan, maps the dialed digits to an electronic address addressable over the PSTN and routes the call over the PSTN to the destination second communication device in the second network region.

International Classification:

H04L 12/26

US Classification:

370236

Abstract:

Methods and systems for supporting the alternate routing of calls between endpoints, such as session initiation protocol (SIP) endpoints, are provided. An inner gateway alternate route (IGAR) application is invoked when the primary, Internet protocol, communication network is overloaded or otherwise unable to handle a call. The IGAR application assigns incoming and outgoing trunks, and serves as a contact point for session managers in routing the trunk call.

International Classification:

H04W 4/12
H04W 4/16

Abstract:

The present disclosure provides a communication system and method, among other things. As a non-limiting example, the method includes receiving a call from a caller, parking the call, and while the call is parked, determining a paging target for the call. The method may further include paging a first target area in an attempt to summon the paging target to retrieve the parked call. The method may further include paging a second target area in an attempt to summon the paging target to retrieve the parked call, receiving a response from the paging target, and based on the response received from the paging target, connecting the paging target with the caller.
