Dreamcall PC-DC server?

[Favrenation]

If I recall correctly, a few people from the site tried to use the dreamcall service over pc-dc servers. However they were not successful. When I went to the planet ring server google code page I read:

VoIP issues

Back in 2000, Planet Ring connections were using dial-up through PPP protocol. Nowadays, most PC are working under a NAT network, and that's the main problem with VoIP.

Planet Rings tries to obtain the other player's external IP from the UDP packets when it is doing the VoIP negociation (Splash and Dreamdorobo games). The problem is that PR gets the local internal IP, instead of the route external IP. So, when it starts sending messages, it sends them to a wrong IP (the other player's local IP).

A workaround we have developed is the 'VoIPEarth' program that does two things:

Capture VoIP packets in promiscous mode.
Craft a new packet with the same content, and the correct address.

Is it possible that this program that was made might make dreamcall work with a pc-dc server? Or was there a central server that was used that has been taken down?
