We like to switch from openser to opensips. Openser is packaged in Debian, also the amd64 distro.
At this moment we are using amd64 machines. I can find the i386 debs in http://opensips.org/pub/opensips/latest/packages/debian/
I am wondering when or if the amd64 debs will be added or if the project will be packaged in Debian?
Right now there is not amd64 package for opensips, but actually I strongly recommend you to compile it from sources on your machine - this is better as you will get a perfectly tuned opensips for your hardware and OS.
