AllStarLink Network
From the AllStarLink home page:
AllStarLink is a network of Amateur Radio repeaters, remote base stations and hot spots accessible to each other via Voice over Internet Protocol. AllStarLink runs on a dedicated computer (including the Rasperry Pi) that you host at your home, radio site or computer center. It is based on the open source Asterisk PBX running our app_rpt application. App_rpt makes Asterisk a powerful system capable of controlling one or more radios. It provides linking of these radio “nodes” to other systems of similar construction anywhere in the world via VoIP. AllStarLink's primary use is as a dedicated computer node wired to your repeater or radio. Connections from Echolink, other VoIP clients and telephone calls are supported.
There are basically two “flavors” of AllStar nodes: those that run AllStarLink software, and those that use HamVoIP software. AllStarLink, or ASL, runs Debian Linux (or Raspian OS, which is based on Debian). HamVoIP runs on an Arch Linux system. The software that handles AllStar voice processing is the same as in many commercial voice-over-internet-protocol (VoIP) systems: Asterisk.
AllStar nodes can utilize radios to communicate with the local node. Nodes can also be created that do not utilize an RF-based radio. Such radio-free nodes are usually connected to the internet via an Ethernet cable or over local WiFi.
You can find the list of active AllStar nodes at https://www.allstarlink.org/nodelist/.
Note that while we list AllStar as an analog system, it can be bridged into digital networks like BrandMeister.
