Broken links and missing manual

It seems that the following domains are down:

  data.gnutelephony.org and wiki.gnutelephony.org

These are pointed to by:

  http://www.gnutelephony.org/index.php/GNU_ccRTP#Documentation

and

  http://www.gnu.org/software/ccrtp/

Are the current versions of the programmer's and reference manuals
available somewhere else?

Thanks.
