Hi Jason,
that would be great!
Did you notice? Fraunhofer Institute is currently working on an Rf
Interface in the S-CSCF...
I wanted to implement the Ro-Interface in the S-CSCF myself (as a step
3), but if you want to do it, go ahead!
My focus is currently on the described developments (first on
implementation of RFC 3680 in Kamailio, then the replacement of the
built-in usrloc within the P-CSCF).
i would feel more comfortable, if i could review your code first,
before i add it to the official Kamailio/sip-router repository....
would that be ok for you?
Thanks for your support,
Carsten

Hi Carsten,
in light of Daniel's response maybe we should join forces? how would you
feel about me contributing the effort you are putting into openims and sr3?
btw, I have already written a module for the Ro interface. What I wanted to
do next was to incorp. code into the dialog module to be able to support
online charging through the Ro interface.
thoughts?
Cheers
jason

Hi,
I will simply forward this question...
I would suppose to put it somewhere at the Kamailio SVN for 1.5?
1.5 is no longer maintained officially, just backports by developers that
still use it -- which may happen down to 0.9 -- but no new features.
Personally I would prefer to go only with one IMS extensions integration,
based on current development branch (git master). Besides the fact that
joining forces will make things move forward faster, having two directions
for same thing (one within very old branch) will confuse people a lot. Maybe
Jason will consider trying 3.1.x and we can try removing his doubts about
this version when he has specific questions about what he does not trust.
I strongly think this is the best at this moment, there is already
confusion with duplicated modules coming from kamailio and ser, creating a
new development branch based on 1.5 will confuse even more. We are working
to remove duplicated, thus remove confusion, and we should go only in this
direction if we want to finish it soon.
Now regarding the trust of 3.x, I can say that 3.1.x is far more better
than 1.5. In 1.x one could barely use tcp or tls, the tm module had some
potential races which couldn't be handled without a major refurbishment.
That happened in 3.x - if one search the recent archive, there were crashes
reported to 1.5 rather than to 3.1.
If one does not like the mix of kamailio and ser modules, then just ignore
the modules_s/* for a while and you are set. Installing kamailio from
packages take care of that and only kamailio modules are installed
(modules/* and modules_k/*). AFAIK, the openimscore developers are working
also with 3.x so future code from them will just work on latest version of
our project.
Cheers,
Daniel

Hey Carsten,
Right now I am doing something similar, but rather with
kamailio-1.5.5. I have not migrated to SR yet and dont intend to
anytime soon. Right now I have ported CDP, CDP_AVP, and ICSCF and they
are running.
My reason is that I don't quite 'trust' sr2 just yet - and I'm not
sure I like the mix and match of ser and kamailio modules - anyway a
discussion probably already discussed and not for this thread. I'd be
happy to put a 1.5.5 version up somewhere that everyone could use?
what do you suggest?
Cheers
Jason

Hi everyone,
i just wanted to notice, that i am actually working on re-integrating
the OpenIMS-core into the sip-router.org/Kamailio project.
It is not a fork of the official OpenIMSCore project, but more a merge
of the OpenIMScore Project into the Kamailio/sip-router.org project.
As a first step, i've made all the CSCF modules compile and work with
a current Kamailio source. In order to do this, only minor adaptions
were required.
As a second step, i am working on a better integration into the
existing structures of the Kamailio project; i want to achieve the
following things:
- replace integrated dialog awareness of the CSCF modules with
Kamailio's dialog module
- replcae integrated registrar of the CSCF modules with Kamailio's
registrar module
- replace integrated nathelper support with the sip-router.org
nathelper/rtpproxy moduels
- replcae integrated RFC 3680 support with Kamailio's
Presence/Presence-User-Agent modules
- add documentation in accordance with the other sip-router.org modules
I've already changed quite a few things in the Kamailio core, in order
to achieve this: K's dialog module is now able to store additional
data to a dialog (works great), K's usrloc/registrar module is able to
store additional information to an contact (still buggy) and i have
already added support for RFC 3680 to Kamailio's presence/pua
infrastructure (when you register, the system will "PUBLISH" the
registration state; another system may already "SUBSCRIBE" to the
status and "NOTIFY" requests are already parsed (but not stored yet)).
So it is going on. I have also already modified some of the config to
use generic append_hf() and remove_hf() functions instead of custom
implemented functions...
The progress is slow but steady since i work on it apart from my
regular work. I try to publish any new developments on this on my
blog/homepage (www.ng-voice.com), where you may also find some more
information about the installation and the components of the project
(i provide a repository of the last step for easy installation).
I started implementing an own HSS some time ago (openhss.org), but the
development on this currently stopped. First, i do not have enough
time to work on both the Kamailio integration, regular work and the
HSS; second the main developer on the HSS (Brian) just resigned due to
health reasons.
Some of you may have noticed, that i am working for Telefonica in
Germany as a regular work. I am working on the Class 4/5
infrastructure at Telefonica and we have already implemented an
Ericsson IMS core. However, i wanted to mention, that neither
Telefonica nor O2 is behind this project. The only support i get from
Telefonica is, that i get a monthly salary and that i may use some
time to work on the OpenIMS-project during normal office-hours (as
time allows).
If i do things, i do it by heart and not half-hearted... that probably
explains a lot of the effort spent on the project.
Kind regards,
Carsten
