@miconda & bogdan_iancu :: It's almost 3 years since your last post. Surely there have been a lot of changes and success in your projects during this period. Will you please share us those information so that we have a clear idea about which one to select.

Thanks in advance

Very amusing, I would say. kamailio (openser) 1.5.0 is already in pre-release phase since 2 weeks ago, see:
http://www.kamailio.org/dokuwiki/doku.php/features:new-in-1.5.x
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:
http://lists.kamailio.org/pipermail/users/2008-November/020693.html
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!

Well, of course that X did this and Y did that...this is not the point.
The point is why kamailio is importing the core and TM from SER project (the number one "enemy" of OpenSER from the first day to now) if there is so much knowledge in working on those pieces of code? because it is not...Just polishing and shiny improvements that any coder can do.

As http://www.opensips.org/index.php?n=Main.Ver15x shows, OpenSIPS still focus (by itself) on work on important things, like security, performance, integration and presence.

Presence (xcap, rls, etc) was worked out during SIPit and tests with other vendors, real Load-balancing (based on load) support is now available, performace was increased with 25% (see http://www.opensips.org/index.php?n=Resources.TestsPrepareStatements)

And all this without keep porting work from other projects or outsourcing the core components to other parties.

In reply to the last comment ...

If developers of core and TM went away from Kamailio, why are there a lot of improvements? I co-founded OpenSER (renamed later in Kamailio) I have been working with core and TM a lot and continue to do so. Apart of three developers, nobody else left Kamailio. 5 out of 7 management members and core developers are in with Kamailio only. Just FYI, try to see the progress in the last three months and then reconsider the "lack of devs" statements:
http://www.kamailio.org/dokuwiki/doku.php/features:new-in-1.5.x

First show the progress in your side, then talk. Regarding the Kamailio developers, check this one:
http://lists.kamailio.org/pipermail/users/2008-November/020693.html

... and again, speak about Kamailio development team when opensips team skills reach same level.

Strange that you are the only one keep saying there is a merge back. Why nobody else does that? It is a joint project, check carefully:
http://sip-router.org

There won't be any lost of OpenSER goals, innovation and flexibility are more encouraged and free to do now upon a better structured environment:
http://lists.kamailio.org/pipermail/users/2008-November/020695.html

So, do no try to spread lies as you have no knowledge of what is going on with kamailio and sip-router.org. Come back later when a new feature is not included, or something else of OpenSER goals is dropped, and have proves for your statements, ... Then we can talk, for now, you just try to mislead in a trivial manner — so sad for you. Focus on your project, make it better — people are smart, will discover and chose the best and most reliable for them. Stop polluting the web with false statements.

Of course a web site cannot provide a comprehensive view over a project. But bottom line, after OpenSER split, the developers for most critical parts (like TM, core, presence, dialog, mediaproxy) went for OpenSIPS - a project (as power to delivered) is defined by the active and skilful developers. Kamailio recently announce merging with SER in order to go back and use the core and TM of SER (probably because of lack of devs) - anyhow, a merging back to SER will invalidate everything that made OpenSER so successful and apart from SER.
OpenSIPS has ongoing work for new a lot of new adds-on - more dialog stuff, prepaid controller, RLS, B2BUA, QoS, advanced routing, real load-based balancing, etc - maybe (as most of the tech guys) the listing of all this on the project web page is not the best (tech guys speak code not words :D).

Ask them both the same question and choose the one from which you will received the quickest response. Cause you don't want do deal with potentially almost dead projects like SER. Stick with the one that will have the biggest dev team and the most active community.

kamailio vs opensips

Posted:Sun 14 of Sep, 2008 (19:42 UTC)
In learning the ropes of VOIP, I had studied OpenSER in the past, and would now like to set up my own voip server. The recent fork in OpenSER leaves me with a lot of questions.

To begin, can someone please explain the basic differences between Kamailio and OpenSIPS? I have read both websites and there is not a lot of info comparing the two, other than generalities like 'consolidated diversity', 'consolidate d view on the project management', etc. I am more interested in the nuts and bolts of the code, and reliability.

Just from my reading, it seems that kamailio is more a continuation of openser, while opensips is a new development model. Would I be better off to stay with one or the other? What are your opinions?
