Unknown host

I was trying to get the sources as the below web manual says but cant reach the cvs.digium.com. with CVSup got this:
cvsup -g -L 2 /usr/src/asterisk-sup
Parsing supfile "/usr/src/asterisk-sup"
Unknown host "cvs.digium.com

Can any one assist me please.

Good evening lance
Actually I think asterisk is using “svn” as repository.
You can check out their repository @ svn.digium.com
You can get more instructions on asterisk.org/developers/get-source
