Terminal-based P2P VoIP application (TeamSpeak-/Skype-like voice chatting over LAN or Internet)

Terminal-based P2P VoIP communication

Todo list

• Get a microphone input stream
• Get a custom version of the speaker module which allows specifiying the output device. (See here)
• Get a speaker output stream
• Pipe a microphone input stream the the speaker output
  • On Ubuntu 16.04 LTS
  • On Raspbian stretch
  • On Fedora 26
• Pipe a microphone input stream over the network into another node process and pipe it from there to a speaker
• The above + the other way around (send+receive audio on both nodes at the same time)
• Allow connecter to reconnect to listener, after connector disconnected or crashed.
• Allow connecter to reconnect to listener, after listener disconnected or crashed. (Untested)
• Test it on Linux
• Test it on Mac OS X (can't; don't own a device)
• Test it on Windows

On Linux it should work fine. At least for me it does.
