Origination Customer

When calls ingress the Orchestrator via an Origination Vendor Trunk Group (Inbound “A” Call Leg). The Orchestrator searches all defined numbers in all Origination Customer Trunks Groups for an exact match to the telephone number provided in the user portion of the Request URI in the incoming SIP Invite message.
