Call outcomes

When an inbound call arrives in Vonage Contact Center, or an agent makes an outbound call, Vonage Contact Center uses a telephony server to connect that call to its target. At the end of the call, Vonage Contact Center assigns one of the following outcomes to the call. In most cases, Vonage Contact Center selects the call outcome based on the Session Initiation Protocol (SIP) code returned by the telephony server.
