 The Session Initiation Protocol (SIP) is a simple text-based protocol that is easy to understand.  SIP has four major functions: a) Locate and end-point, b) Initiate a signal, c) Ensure compatibility and start a session, d) Terminate the session

With SIP you have to solve five major problems:  Caller-I.D  Called Party I.D  Media Privacy  Media Authentication  Signaling Confidentiality

 There is no way of asserting that the calling party is an authenticated user/peer on the network.  To understand the security detail & to suggest a better deployment technique.

 Provides communication security over Internet.  Session key used to encrypt data flowing between parties.  Property : Forward Secrecy  TLS is successor of SSL(Secure Socket Layer).

 Library that asterisk requires to use TLS is not there.  Old version of open SSL  SIP registers work but secure TLS need to be secure with asterisk  “Polycom” version of TLS could be outdated, compared to astersik- required new phones.  SSL on phone & server are incompatible.

 Whether or not all methods have been used.  Few VoIP service providers use these techniques.  No permanent reduction of the effects of SIP hacks & security related problems.  SIP can revolutionize the VoIP industry now with the advent of VoLTE.  But only if the security, media privacy and authentication issues are addressed and solved.
