High Quality Content by WIKIPEDIA articles VoIP User is a community driven and financed SIP based VoIP network. The projects aim is to introduce people to the concept of VoIP by allowing members to experiment with SIP and IAX2 devices.The VoIP User network was designed to operate within a community environment and therefore differs substantially from most other VoIP networks. The main highlighted difference being that users can call PSTN phone numbers through VoIP Users PSTN gateway without incurring any call charges. The way that VoIP User is funded is noteworthy: Calls into VoIP Users numbers generate a small amount of per minute revenue (the termination charge ), and this money goes into a community account or pot.
