To check out all source code (trunk, branches and tags) directly from project's SVN use:
# svn co https://opensips.svn.sourceforge.net/svnroot/opensips opensips
The above command will download everything -- all branches and tags so far. It is better to download desired versions only, otherwise the size can be quite big.
