I would like to build a VPN Tunnel server to bypass firewalls. Can u do this job? Once completed we will build to bypass firewalls and blockages of VoIP blocked countries and link it to our dialers so clients in those countries can use their dialers and make calls since there VPNs will bypass those blockages. This is essentially necessary in that it will help to bypass firewalls and VoIP blockages set by some countries that restrict VoIP in their countries especially in the middle East.
