The call may be forwarded by the call routing device to a call agent device. The device may also establish a session with the call agent device to which the call is forwarded by the call routing device and automatically receive, from the call agent device, a message that includes an identifier for a virtual call agent. The device may extract the identifier from the received message, compare the extracted identifier to an identifier that is associated with the call, and determine whether the call routing device correctly forwarded the call based on the comparison."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Testing call routing","description":"A device may automatically place a call to a call routing device based on one of a list of numbers or addresses.
