If you can adapt it to rtpp_2_0 that would be great. This is our latest production code and it's pretty much superset of the 1.x feature and performance wise. I've just pushed some fixes to get it compile cleanly on Ubuntu using just GNU make.
Are you guys registered on github? I've been trying to add you to the repository ACL list but could not find anyone. Jev is off for few days, but he should be back tomorrow to finish migration of the website etc. Thanks! -Maxim On Fri, Jun 27, 2014 at 7:51 AM, Răzvan Crainea <raz...@opensips.org> wrote: > Hi, Maxim! > > Good news, I am glad you are interested in these features.
