Publication number: 20150304504Abstract: A method for performing alternate and therefore least cost routing in distributed H.323 Voice over IP (VoIP) networks is provided. With this method, the VoIP network consists of a hierarchy of gatekeeper (GK) functions to provide alternate routing, network element redundancy, and scalability. The alternate routing function is performed by a directory gatekeeper with route selection advancing from a first route to a second route by either of two conditions: (1) there are no resources available to terminate the call in the first zone; and (2) a lack of response to the directory GK request for such resources.Type: ApplicationFiled: February 3, 2015Publication date: October 22, 2015Inventors: David Frederick McGuigan, Harry Edward Mussman, John Joseph McCabe, Robert Kellar Israel, Eric Richard Sporel

Patent number: 8213442Abstract: A method and system is provided for performing inbound call screening in a packet-based network, such as an H.323 Voice over IP (VoIP) network. The inbound gateways on the network are registered with inbound gatekeepers, and standard messages are used between an inbound gateway, an inbound gatekeeper and an inbound screening database to decide: whether an inbound call to a particular called number (DID) is to be allowed into the network; whether the called number should be translated into a different called number; and whether a routing index should be included in the called number to indicate the destination of the call.Type: GrantFiled: August 3, 2009Date of Patent: July 3, 2012Assignee: Level 3 Communications, LLCInventors: Harry Edward Mussman, Tanrushree Singh, John Joseph McCabe

Publication number: 20080070528Abstract: A mid-call feature of a voice call server, such as an IP PBX or IP Centrex system, is accessed during a call. During the call with a mobile terminal via a mobile telephone network, a voice call signal associated with a mid-call feature from the mobile terminal is passed over a mobile telephone network to a first communication system. The voice call signal is converted to a data call signal at the first communication system, and the data call signal is transmitted to a second communication system over the data network. The method can also include providing the mid-call feature in response to receipt of the data signal at the second communication system.Type: ApplicationFiled: September 19, 2006Publication date: March 20, 2008Inventors: Tom Joyner, James D. O'Brien, Harry Edward Mussman

Patent number: 7346043Abstract: Methods are described which enable the operator of a network such as an Internet protocol (IP) network to allocate ingress and egress channel capacity for the use by different services or for use by different service providers. The methods can prevent a service provider or a service from overusing network capacity. The methods also enable the network operator to temporarily allocate unused capacity if demand for a service exceeds previously allocated capacity. Further a method is described whereby capacity on a Voice over Internet protocol (VoIP) network is sold to service providers with guarantees for the number of available channels, where the channel capacity guarantees could be global, or by any type of subdivision. In addition to having a committed channel capacity, the service provider could be allowed to exceed the committed capacity whenever excess capacity is available on the network.Type: GrantFiled: May 30, 2002Date of Patent: March 18, 2008Assignees: Verizon Corporate Services Group Inc., Level 3 Communications, LLC, BBN Technologies Corp.Inventors: Robert Olshansky, James D.

Patent number: 6243388Abstract: A network (10) includes a broadband customer service module (B-CSM) (20). The B-CSM (20) includes a plurality of feeder interface cards (FICs) (36) and optical line cards (OLCs) (38) which are coupled together through a midplane assembly (34) so that each FIC (36) couples to all OLCs (38) and each OLC (38) couples to all FICs (36) through junctor groups (68). Within the B-CSM (20) circuit switching is performed electrically at an STS-1 rate. A reference clock which oscillates at a frequency slower than the data rate is routed with payload data so that it receives delays similar to those imposed on the payload data due to processing. At second stage switching fabrics (50) where data need to be extracted from signals flowing within the B-CSM (20), a clock regeneration circuit (32) generates a master clock signal oscillating at twice the data rate and phase synchronized to a delayed reference clock.Type: GrantFiled: December 30, 1997Date of Patent: June 5, 2001Assignee: Verizon Laboratories Inc.Inventors: Harry Edward Mussman, Stephen S. Liu, Thomas R. Helmes
