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
