NOF Indications
RTP_INDICATION
4.23 RTP_INDICATION
This indication is generated when one of the following occurs:
• An RTP connection is connected or disconnected.
• The active session count changes.
• The connection performs a path-switch.
When the connection is disconnected, final RTP statistics are returned. At other times the rtp_stats parameter is
reserved.
