These programs are clients for the NXDN networking now built into the MMDVM Host.
The Parrot is very simple minded and can only handle one client at a time and is therefore not suitable for use as a shared resource via the Internet.
The Reflector is used as a single talk group in the same way that it is with P25. It also includes the option to link it to NXCore to allow for interchange of audio between the two. At the NXCore end, it should be set up to receive the traffic from only one talk group.
The Gateway allows for use of NXDN Talk Groups to control the access to the various NXDN reflectors. It speaks the same language as Icom repeaters to the MMDVM so could theoretically be used as a gateway for a real Icom NXDN repeater. This has not been tested.
The Gateway has an ini file that contain the parameters for running the software. The filename of the ini file is passed as a parameter on the command line. The Parrot takes the UDP port number to listen on as an argument.
The MMDVM .ini file should have the IP address and port number of the client in the [NXDN Network] settings.
They build on 32-bit and 64-bit Linux as well as on Windows using Visual Studio 2017 on x86 and x64.
