Title: **Innovator Spotlight: Xiaodong Zhu and His Contributions to VoIP Technology**

Introduction

Xiaodong Zhu is a notable inventor based in Fremont, CA, who has contributed significantly to the field of Voice over Internet Protocol (VoIP) technology. With two patents to his name, he continues to push the boundaries of innovation in communication systems, particularly in enabling users to connect seamlessly despite the challenges posed by network firewalls.

Latest Patents

One of Xiaodong Zhu's latest patents addresses the issue of enabling incoming VoIP calls behind a network firewall. This invention involves a network device that receives a registration message from a private user device, which includes its private Internet Protocol (IP) address. A public IP address and discrete port number are assigned to this private user device and stored in an incoming call table. This registration message is then translated to include the new public IP address and port number before being forwarded to a proxy server for registration.

When an incoming call invitation message is received from a public user device, the device directs it to the public IP address and port number. The technology then translates the call invitation message to include the private IP address based on the information stored in the incoming call table, allowing the call to be successfully forwarded to the private user device. This innovation ensures secure and effective communication, eliminating the barriers that firewalls typically create.
