Cisco Cisco Computer Telephony Integration Option 8.5 Developer's Guide

The RTP_STOPPED_EVENT message indicates that an RTP media has been stopped.  There are two 
media streams for audio media so there will be two RTP Stopped events, one indicating the input has 
started (i.e. the phone is not listening) and the other that the output has started (i.e. the outgoing media 
from the agent phone has stopped).

The RTP_STOPPED_EVENT will be received when the call is placed on hold, and when the call 
disconnects.
