 TOPIC : SECURITY REQUIREMENTS AND CONSTRAINTS OF VOIP(Voice over IP).

 GOALS:

 Voice over IP (VoIP) is a technology by which voice can be transferred from 
 circuit-switched networks to or over IP networks, and vice versa. although 
 at the current  moment , it's attractiveness is low cost, in the long run ,
 the value added  services will support to emerge VoIP.

  security mechanisms developed for VoIP have some faults and lot of them yet to be solved.
  With the convergence of the voice and data worlds the real similarities of the 
  security concerns will become apparent. objectives of this paper are to introduce
  to the security problems in some existing VoIP architecures and security constraints 
  imposed by some selected VoIP architectures.

 SCOPE:

      >> characteristics of existing VoIp protocols(security).
      >> security requirements
      >> security constarints
      >> solutions to the some of the security problems discussed
      >> Related research
      >> conclusion
