I’m putting my money where my mouth is and funding development of STUN support for the Asterisk open-source PBX. I’m not a regular contributor to Asterisk and I’m quite a bit outside the Asterisk inner-circle, so we’ll see if this code ever makes it back into the Asterisk CVS.
Karl Brose is writing the code and he is making good progress, although a recent hospital stay has caused a slight setback.
UPDATE: December 2004. I’ve lost touch with Karl and I simply have not had time to complete the work. I have a working snapshot of patches to an earlier CVS release of Asterisk. I have even been too busy to clean up and publish the patches. If anyone would be willing to volunteer to help, drop me an email at mrblog AT mrblog dot org.
