Parties
A party represents one of possibly many leaves of a point-to-multipoint connection. When making an outgoing call, a connection-oriented client can specify a party. This makes the call a multipoint call, with the client acting as the root of the call and the remote party as a leaf. The client can then request that additional remote parties be added as leaf nodes to the call.
