SIPproxy64/6bed4[0cpm free calling -- till 2012/12]
This is an additional project to the ongoing 0cpm project which is building the IPv6-only telephony. This particular projects intends to provide a peering platform allowing for building a network to interconnect telcos, PBX farmers and connections handlers.
What's unique here is systematic deployment of IPv6 and the use of RTT (real-time text) within ordinary telephone systems wherewith e.g. deaf people can communicate as if they are speaking. The use of open source firmware for SIP phones in this project is groundbreaking.
