In this scenario, the provider is set up to auto-answer a new call. The provider answers it and determines the call's media mode. It then informs TAPI of the call. Because no applications decide to take ownership, TAPI cannot pass the call to any application.
The following steps describe what occurs in a scenario in which a line has only monitoring applications, the service provider is configured to auto-answer all new calls, and a call comes in.
This example illustrates an important point for writers of monitoring applications. It is not a good idea to wait to monitor for incoming calls you later want to own. It is better to open the line as an owner, because there might not be enough time to change your privilege from monitor to owner before TAPI drops the call.
