Abstract:
1. A method for tracking telecommunication services comprising: receiving at a filter node a call packet from a first node included in a plurality of nodes, wherein the call packet includes a call identifier identifying a call associated with the call packet; determining at the filter node a filter status of the call; registering the first node and a second node with the filter node in response to receiving an open message, the open message identifying a node operable to receive messages from the filter node, the registering the first node and the second node enabling the filter node to communicate one or more filter statuses to the registered first and second nodes; determining at the filter node, based on stored dynamic node information, to which of the plurality of the nodes to transmit one or more notification messages; transmitting, based on the determination, the one or more notification messages from the filter node to the first node from which the call packet was received and the second node, wherein the notification messages identify the call identifier and the filter status of the call and wherein the notification messages conform to a protocol that primarily communicates tracking information; and forwarding the call packet to the second node.
