The IP conferencing components include ipconf.tsp and confmsp.dll. These two components are paired together within TAPI 3.1 architecture to support IP multicast audio/video conferencing.
The ipconf.tsp is a standard TAPI 3.1 compliant telephony service provider (TSP). It is responsible for IP multicast call signaling. Through other TAPI 3.1 components, it forwards to confmsp.dll multicast call information, contained in a blob of session description protocol (SDP).
The confmsp.dll is a standard TAPI 3.1 compliant media service provider (MSP). It receives from ipconf.tsp call information. Based on the call information, it builds DirectShow filter graphs to construct audio/video IP multicast streams. The MSP supports standard MSPI methods and exposes interfaces that allow control over individual participants in a conference.
There are no configurable requirements for this component.
