Each session must be created and then activated.
To create a session, use IRTCClient::CreateSession.
To activate a session, after the connection is established, use IRTCSession::AddParticipant.
If the URI is an email address or telephone number, the session is initiated through the SIP proxy server.
If the IP address or machine name is entered, a direct peer-to-peer communication link is set up. A SIP proxy is not used and is not required.
