The IRTCInfoEvent interface gives access to information contained in an incoming SIP INFO message. RTCE_INFO events have an IRTCInfoEvent interface.

When the application's implementation of the IRTCEventNotification::Event method indicates an RTC_EVENT of type RTCE_INFO, the method's pEvent parameter is an IDispatch pointer for the IRTCInfoEvent interface.

Note  You must call the IRTCClient::put_EventFilter method and set an event filter mask that includes the RTCEF_INFO event to enable reception of info events. If you do not call IRTCClient::put_EventFilter, your application will not receive any events.
