DSG NAT Proxy is a complete solution to solve complicated network problems that may happen when enterprises use the IP PBX Communication System.

Because of the lack of IP addresses, many Internet facilities including Blaze or Savanna Series IP PBX Communication Systems must be installed behind NAT or firewall. When IP PBX system travels through virtual or floating IP, sometimes the voice packets cannot traverse NAT or firewall successfully and cause the problem of one-way or failed phone communication.

To solve this problem, you may create some service ports on NAT or firewall; however, it requires someone who is familiar with the Internet environment and facilities to set up and some local ISPs do not allow users to create other service ports.

DSG NAT Proxy provides a complete solution to solve the problem. With DSG NAT Proxy, Blaze or Savanna IP PBX Communication Systems and Off-Premises Phones can traverse more than 95% of NAT or firewall successfully without creating other service ports, and therefore enterprises can communicate via IP-PBX Communication System with pure and stable voice quality.
