ITMedia::get_TransportProtocol method
[ Rendezvous IP Telephony Conferencing controls and interfaces are not available for use in Windows Vista, Windows Server 2008, and subsequent versions of the operating system. The RTC Client API provides similar functionality.]
The get_TransportProtocol method gets the transport protocol. This is specified in addition to the media format so that the same standard media format may be carried over different transport protocols even when the network protocol is the same, such as with Vat PCM audio and RTP PCM audio.
