Hello,
Claudio Furrer elcaio@gmail.com has now git commit access for his work on gentoo packaging. He create several patches and extensions for our gentoo package files in the last months and also maintain an own unofficial portage overlay tree at http://gpo.zugaina.org/net-misc/sip-router since some time.
He just updated the gentoo packages in git master today, so if you're an gentoo user why not just give it a try - he is looking forward to your feedback.
Welcome Claudio!
Best regards,
Henning
