Voice over IP (VoIP) presents totally different
challenges than a public switched telephone
network (PSTN). It runs on the web and inherits
many challenges for VoIP service providers on a
way to secure VoIP system. Until now, security
has been overshadowed by the attractiveness of
VoIP technology.
Security Risks Meanwhile, VoIP traffic remains on
networks that arent sufficiently protected. This
infrastructure includes personal branch exchange
systems gateways proxy, registrar and locator
servers, and phones. every VoIP component is
available and accessible over the information
network. Therefore, before deploying VoIP system
you need to remember its security risks and also
the countermeasures. In fact, the potential
threats area unit numerous and embody, as an
example, attacks on the confidentiality,
integrity and accessibility of the system.

• How to Secure VoIP System
• First of all, carefully choose proper VoIP
  protocols. The equipment should satisfy your
  requirements
• Especially relevant is to disable unneeded
  protocols, which could harbour unknown
  vulnerabilities
• Perform a security audit of each VoIP element
  that is accessible on the network. Check
  telephones and terminals. VoIP elements are
  software components running on hardware. Make
  sure its possible to manage the underlying
  operating system
• Separate the VoIP and other IP-based
  infrastructure using logical or physical
  separators
• Authenticate remote operations. Noteworthy to use
  only an authorised personnel from authorised
  locations
• Make sure the VoIP security system will track the
  communications ports by reading within the
  signalling packets to find the chosen ports and
  enable two endpoints to send media packets to
  every other
• Noteworthy to include your VoIP servers in the
  tape backup schedule. Without a backup, you will
  be unable to restore telephony
• Use Network Address Translation (NAT), because it
  converts internal IP addresses into a single,
  globally unique IP address for routing across the
  Internet.

exhaustive and only includes some of the most
common tips for mitigating security
issues. iNextrix, along with providing VOIP
