RTP_STOPPED_EVENT
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.
Table 5-26 defines the format of the RTP_STOPPED_EVENT message:
SendingAddress The IP Address that the client is sending the RTP
stream to.
STRING 16
SendingPort The UDP port number that the client is sending
the RTP Stream to.
