Abstract: Systems and methods are disclosed for detecting security threats in a network environment. A canine detection unit may initially inspect items at a screening location. A local workstation is used to further inspect the items that are identified as raising potential security concerns. Requests for assistance are submitted to remote experts for assistance with resolving the potential security concerns. One or more servers receive the requests over a network and retrieve dialing plans associated with the origins of the requests. The one or more servers utilize the dialing plans to route the requests to expert groups assigned to dialing plans. In response to the requests being accepted by remote expert devices in one of the expert groups, the one or more servers establish connections between the local workstations and the remote expert devices that accept the requests.
