Maybe uploading it (a tarball if big or just the patch file) on the 
tracker is another quite easy possibility. Either on the one from 
sip-router.org, or, since it is 1.5, can be even on the sourceforge.net. 
This will allow to upload new versions of the files if changes are 
needed in the future. Then provide the link to the tracker item on the 
mailing list.

I would prefer no commit on the mainstream SVN branches, so we do not 
open past releases, that will create lot of confusion.

Cheers,
Daniel
