  • Patent number: 8144713
    Abstract: Virtual dedicated voice connections between parties to a packet-switched system can be created by reserving capacity for such connections in the packet-switched system. The capacity reservable by any one party is limited to prevent over-subscription of resources in the packet switched. The system incorporates a call admission control processor for controlling access to the packet-switched call routing system such that a voice call attempt is successful only if capacity for such a dedicated connection has previously been reserved. The capacity reserved for the virtual connections is made available for use by other traffic when not required for voice sessions.
