0 Cost Telephony System

Traversing Network Address Translators (NAT) is one of the most challenging works for providing real peer-to-peer Internet telephony services for end users. This new technology can provide seamless Plug-n-Play without changing NAT’s settings. No more port forwarding, no more external proxies to redirect packets, no more limitations in IP address types (Fixed, Dynamic, Real or Virtual IP) and no more phone bills to pay. No matter where you are, as long as you are roaming over the Internet. You can be reached by a unique virtual phone number, just like your cellular phone.
