OpenVoIP: An Open Peer-to-Peer VoIP and IM System
Welcome to OpenVoIP, an open source peer-to-peer VoIP and IM system of ~1000 nodes running on ~300 PlanetLab machines. OpenVoIP runs Peer-to-Peer Protocol (P2PP) which can be used to implement well-known DHTs or unstructured protocols. Unlike OpenDHT, where it was only possible to put/get the data, we allow non-PlanetLab nodes to become part of our overlay. This means that you can download the P2PP executable for Windows XP, Linux, or OpenWengo-P2PP SIP phone and connect to our overlay. Your node will provide routing and storage services to the overlay.
This software project appears to be in the experimental phase.
