Unified session detail records

A unified session detail records of a multi-hop session is provided. The multi- hop session may be established through multiple nodes in a VoIP network. Each node may generate session detail records for the legs of the multi-hop session that are connected to the node. The nodes on the path of the multi-hop call may send the record to a single node to consolidate the session detail records of the legs of the multi-hop cal in the single node so that the single node can provide unified session detail records of the multi-hop session. By providing unified session detail records, the user does not need to track down the nodes that are on the path of the multi-hop call to obtain the session detail records of the multi-hop session.
