VoIP on AREDN: Exploring Cisco IP Phones for Mesh Networks

As I continue experimenting with AREDN (Amateur Radio Emergency Data Network), I’ve been diving into VoIP (Voice over IP) communications using Cisco IP phones. While AREDN is known for supporting data, file sharing, and chat, integrating VoIP offers a whole new level of practical, real-time communication across a mesh network.

After ordering some Cisco SPA525G2 phones, I’ve successfully set them up to communicate directly over my AREDN nodes using direct IP dialing, and the experience has been incredible!

Trying AREDN with GL-AR300M16-Ext Mini Smart Routers

I recently decided to give AREDN (Amateur Radio Emergency Data Network) a try. To get started, I bought two GL-AR300M16-Ext mini smart routers, which are affordable and well-supported by the AREDN firmware. Flashing the firmware onto the routers was straightforward following the official instructions, and after the basic setup—including giving each node an appropriate name — I was able to log into both routers without any issues.
