The following figure illustrates the TLS messages exchanged between the IP phone and
TLS server to establish an encrypted communication channel:
Step1: IP phone sends “Client Hello” message proposing SSL options.
Step2: Server responds with “Server Hello” message selecting the SSL options, sends its
public key information in “Server Key Exchange” message and concludes its part of the
negotiation with “Server Hello Done” message.
Step3: IP phone sends session key information (encrypted by server’s public key) in the
“Client Key Exchange” message.
