RVSIP_TRANSPORT_CONN_TLS_STATE_UNDEFINED
No TLS sequence was initiated on the connection.
RVSIP_TRANSPORT_CONN_TLS_STATE_HANDSHAKE_READY
The connection is TCP-connected and ready to start the TLS handshake. To
move the connection to the TLS_CONNECTED state, call
RvSipTransportConnectionTlsHandshak().
RVSIP_TRANSPORT_CONN_TLS_STATE_HANDSHAKE_STARTED
The connection started the handshake process.
RVSIP_TRANSPORT_CONN_TLS_STATE_HANDSHAKE_COMPLETED
The handshake procedure on the connection was completed. Post connection
verification might still be needed if the connection requested the certificate of
the remote party.
RVSIP_TRANSPORT_CONN_TLS_STATE_CONNECTED
Data can be sent on the connection.
RVSIP_TRANSPORT_CONN_TLS_STATE_HANDSHAKE_FAILED
The TLS handshake failed. No data can be transmitted on the connection.
RVSIP_TRANSPORT_CONN_TLS_STATE_CLOSE_SEQUENSE_STARTED
The connection has received or sent a close request but is not closed yet.
RVSIP_TRANSPORT_CONN_TLS_STATE_TERMINATED
The connection is terminated. After this point the connection may not be
accessed again.
