Very amusing, I would say. kamailio (openser) 1.5.0 is already in pre-release phase since 2 weeks ago, see:
It outperforms in all aspects the additions in opensips which still does heavy development to catch up. Apart of sanity module, everything is brand new in kamailio. Can you explain how were the presence_dialoginfo and pua_dialoginfo added to opensips? Simply copy from kamailio and few small tweaks.
Also, the caching system in configuration file exists in kamailio since several months ago, via htable module. You added 2-3 weeks ago, under different name and slightly different approach - same cat with different hat. Prepared statements exists in SER since years ago. I couldn't see where is the originality in opensips, there is nothing new there, just re-painted stuff from other projects. Ahh, maybe that centrex module which is a sql query and can be done in kamailio config file in 5 lines.
From the performance document you mention I understand opensips aims to be a frontend to database servers if an increase to sql query has same or higher impact in overall application.
You seem to be in war with everyone, all are enemies. I am one of the founders of OpenSER, nobody was my enemy, cannot tell about you, though.
Stop insulting others, check the team behind the project:
The knowledge of the devel teams differs a lot, opensips has long way to catch up.
If you are as good as you claim, why nobody else says that? TM and core still has 80% of FhG Fokus code, after 4 years, you did just some small additions. All the flexibility that made openser successful, like variables, transformations, config file language (while, switch), belongs to others. Because you changed t_relay_to_udp(...) in t_relay("udp:...") makes you a great programmer with lot of knowledge, then be happy - I have nothing against!
Let the others alone, focus on your project, show what you have good, do not care about the others, it is their job to show what they have done good. People are smart and they will choose the best.
Stop insulting, stop removing others' posting and content from web ... simply grow up!
