Setting up an Enterprise for Secured VoIP Infrastructure

Many enterprises are currently are contemplating on moving from traditional phone service to VoIP. Since VoIP isn't inherently secure, it is necessary for companies to strongly consider what can be done to secure VoIP communications. This project deals with four areas that enterprises need to address to provide a complete and secure VoIP setup.

1) Constructing a secured SSL/TLS based proxy server.

2) Configuration VoIP traversal through the existing firewall / NAT

3) Placing VoIP equipment on a separate VLAN from the rest of the network

4) Install and verify enterprise level VoIP security monitoring.

Many issues relating to end point authentication, secure tunneling of SIP messages and Quality of service etc. are being studied as part of this project
