Understood about the half-duplex communication, but I’m trying to keep this as close to as standard PSTN usage as possible. My goal for this project is to allow an independent journalist in a hostile country or a censored user that happens to not have any technical knowledge other than to connect a soft phone to a username and a password via a a relay or a bridge and make that phone call to communicate to the world what is really going on.

Half Duplex communications are great, but Gulf War I proved to the world how valuable full duplex, real time audio communication can be in a given situation, especially in a situation where no one else is able to provide the world that insight.

For the switching portion of this project - once we’ve proven a concept we need to get a project page like has Iain has suggested. I hope that the switching project’s switches will be required to have open IAX2 interconnect policies and a master directory of “Area” Codes :P.

Thanks,

Conrad
