     * call created using

     * {@code TelecomManager#addNewIncomingCall(PhoneAccountHandle, android.os.Bundle)}.

     * Calls of this type are created using

     * {@link TelecomManager#addNewUnknownCall(PhoneAccountHandle, Bundle)}.  Unknown calls

     * are used for representing calls which become known to the {@link ConnectionService}

     * midway through the call.

     *

     * For example, a call transferred from one device to answer would surface as an active

     * call in Telecom instead of going through a typical Ringing to Active transition, or

     * Dialing to Active transition.

     *

     * A {@link ConnectionService} can return {@code null} (the default behavior)

     * if it is not able to handle a request for the requested unknown connection.
