This read-only INTEGER reports the Cast Type of the call: p2p(1) for point-to-point, p2mp(2) for point-to-multipoint, or mp2p(3) for multipoint-to-point. An administrator uses this to understand the topology of a specific call, since a p2mp call fans out to multiple leaves and needs different diagnostic handling (such as the Leaf Reference used in connection tracing) than a simple point-to-point call. For example, seeing cwspCallCastType report p2mp(2) tells an operator that this call may have multiple destination leaves, so cwspConnTraceLeafRef will matter when tracing that specific connection.
