Publication number: 20150264089Abstract: A voice over Internet protocol communication system and method provides infrastructure components as intermediaries between networks, the components include multi-protocol session controllers and a multi-protocol signaling switch as well as a management system. The session controllers process calls and participate in the calls that flow through it. The session controllers process calls that are either at the edge of the network or at the core of the voice over Internet protocol network. The session controllers associate calls with one another in call peers for incoming calls as ingress call peers and for outgoing calls as egress call peers. A centralized database of call routing policies is provided to the session controllers. The session controllers provide cost management, topology hiding, and inter-working, or conversion, of calls from SIP networks to H.323 networks for both voice and video.Type: ApplicationFiled: June 1, 2015Publication date: September 17, 2015Applicant: GENBAND US LLCInventors: Sridhar Ramanchandran, Paritosh Tyagi, Saravanan Mallesan, Gaurav Kulshreshtha, Rohini Raman, Medhavi Bhatia, Sohan Shetty

Publication number: 20140321453Abstract: A method for routing media calls over a real time packet switch connection includes providing a session controller for connecting to a network. The method further includes providing a signaling switch for connecting to the session controller. The method further includes controlling call routing in the network with the session controller where the call routing control includes identifiers for elements in at least two layers of a seven layer model. The call routing control includes a preference for a codec for the call. The call routing is carried out taking into consideration a mean opinion score qualifier from previous calls having a same source and destination.Type: ApplicationFiled: April 30, 2014Publication date: October 30, 2014Applicant: GENBAND US LLCInventors: Sridhar Ramachandran, Paritosh Tyagi, Saravanan Mallesan, Gaurav Kulshrestha, Sohan Shetty, Rohini Raman, Medhavi Bhatia

Patent number: 8509218Abstract: A method includes receiving, at a session controller, session data from a session-detail record. The session data is associated with at least a portion of a call over a Session over Internet Protocol (SoIP) network. A priority indicator associated with an Internet Protocol (IP) packet transmitted over the call is modified at the session controller based on the session data. The priority indicator indicates a priority to transmit the IP packet.Type: GrantFiled: September 29, 2006Date of Patent: August 13, 2013Assignee: Genband US LLCInventors: Medhavi Bhatia, Sridhar Ramachandran, David E.

Patent number: 8254265Abstract: A session controller configured to receive a data packet from a packet-switched network having multiple communication links is disclosed. The disclosed session controller is further configured to define a call-routing policy based on layer-five information, layer-two information, layer-three information and layer-seven information from the data packet. The call-routing policy is configured to define a least-cost routing (LCR) call route for an ingress call over at least one of the plurality of communication links. The LCR call route is associated with an operational cost that is lower than an operational cost associated with at least one other call route over at least one communication link from the plurality of communication links. The session controller is also configured to associate the ingress call to an egress-call peer based on the call routing policy.Type: GrantFiled: June 28, 2006Date of Patent: August 28, 2012Assignee: Genband US LLCInventors: Sridhar Ramachandran, Paritosh Tyagi, Saravanan Mallesan, Gaurav Kulshreshtha, Sohan Shetty, Rohini Raman, Medhavi Bhatia
