Unlock the power of **Grandstream’s new ZeroTier integration** with this in-depth tutorial and collaboration with Tony at Quik Tech Solutions. In this step-by-step guide, we show you how to set up peer-to-peer communication between two Grandstream GCC appliances using ZeroTier’s software-defined networking. Learn how to configure ZeroTier, build secure site-to-site links through CGNAT or double NAT, and connect built-in UCMs for seamless VoIP calling across locations—just like working in the same office.

If you’re an IT pro, sysadmin, or homelab enthusiast looking for secure, flexible networking without firewall headaches, this video is for you.
