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.

Method and system for routing media calls over real time packet switched connection

A session controller coupled to a database and configured to receive an indication associated with an ingress call is disclosed. The disclosed session controller is further configured to compare at least one of a network capacity, a call-peer bandwidth, or a number of active call-legs associated with the ingress call session against a respective threshold, and to reject the ingress call when a respective threshold is exceeded.

Methods and apparatus for controlling call admission to a network based on network resources

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.

Voice over IP (VoIP) network infrastructure components and method

In a method and system for managing at least one media stream from a media source to a media destination, where the media stream passes through at least one network, providing a media manager for managing the media stream and the at least one network for performing at least one of the management functions bandwidth management, media hairpin detection, media path control, equal access or preventing media backhauling. In the media manager at least one of the media stream information types media routing, receive transport address, routed receive transport address, source network, destination network, media stream identifier, or bandwidth of the media stream is stored for a time period during which the media stream exists in the at least one network. The media manager uses at least one of the stored information types for performing at least one of the management functions.

Media stream management

A method for multistage routing of packets using call templates is disclosed. An ingress call is filtered based on a plurality of ingress-call parameter values. A parameter value for the ingress call is modified based on a plurality of ingress-call-peer parameter values. A filtered ingress-call parameter value and at least one filtered ingress-call-peer parameter value from a plurality of ingress-call-peer parameter values are converted to an egress-call parameter value and an egress-call-peer parameter value, respectively. An egress call is filtered based on a plurality of egress-call parameter values. A parameter value for the egress call is modified based on a plurality of egress-call-peer parameter values.

Methods and apparatus for multistage routing of packets using call templates

A session controller configured to be coupled to a communications network is disclosed. The session controller is configured to receive an indication of a Voice over Internet Protocol (VoIP) registration request at a first time from an endpoint having a third-party registration, and to receive a signaling message from the endpoint at a second time later than the first time. The session controller is further configured to forward an indication of the VoIP registration request and a signaling message to an application server, such that at least a portion of the topology of the communications network beyond the session controller is hidden to the endpoint.

Methods and apparatus for forwarding IP calls through a proxy interface

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.

Methods and apparatus for routing IP media data based on cost

A session controller configured to be coupled to a database and configured to receive an indication associated with an ingress call is disclosed. The session controller is further configured to query the database for an ingress-call peer associated with the ingress call, and to query the database for a dynamic-peer-definition template associated with the ingress call when the ingress-call peer is not identified upon query of the database. The session controller is further configured to reject the ingress call when the dynamic-peer-definition template is not identified upon query of the database.
