Sources haven't been released yet as of 15/12/2005.
I'll post again about it when the sources are out there. Still it looks very promissing.

Edit: It is actually released as open source, at least the modified iaxclient library has been released on sourceforge under the LGPL here:

"Tipic Inc. is proud to announce the born of the first Open Source, P2P, VoIP and Video conferencing solution for XMPP/Jabber. The target of this project is to develop a new portable set of codes using high quality libraries to add VoIP and Video to XMPP"
