Applications can also use switch channels to route voice data to more than one RTP (IPv4 or IPv6) endpoint. This mechanism allows applications to monitor the voice data transferred across a particular voice channel. The following illustration shows the components used to connect voice data to multiple RTP endpoints.
MSPP simplex switch connection
When creating switch connections, the RTP endpoint that receives the incoming data must either be an RTP full duplex or RTP receive endpoint. The RTP endpoint that transfers the data back to the network must be either an RTP full duplex or RTP send endpoint. Because MSPP switch channels are always simplex (unlike voice channels which can be simplex or duplex), applications must connect two switch channels to create a full duplex connection between RTP endpoints. For more information about RTP switching connections refer to RTP switching channels or to the Fusion Developer's Manual.
