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 call 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.

Unified session detail records

An inter-machine trunk (IMT) is provisioned between two witches through an ATM network. The IMT includes a number of virtual connections (VCs) and cell slots within each VC for carrying telephone calls. The IMT is established by multiple repetitions of an inter-switch signaling process, each resulting in the creation of one VC. The number of VCs and cell slots for the IMT is selected based on provisioning information from a network operator. The IMT may be either a pre-established IMT (&ldquo;PIMT&rdquo;) or an on-demand IMT (&ldquo;VIMT&rdquo;). A PIMT is a quasi-permanent connection set up and torn down by an operator to provide some guaranteed data-carrying capacity on the IMT. A VIMT is created automatically upon receipt of a call when no connections are available on the IMT. An IMT can use both a PIMT and a VIMT. When a call request is received at a switch, a call processor determines whether the IMT is to carry the call. If so, a VC of the IMT is selected, and a call request message identifying the called user and the selected VC and cell slot is forwarded to the remote switch. Each switch establishes a connection between the selected VC/cell slot and a respective telephony interface circuit to the calling or called party, as appropriate. The VC/cell slots are identified in both switches by Trunk Circuit Identifier Codes (TCICs) allocated when the IMT is established.
