lockup("location") doesn't find a "sip" registration if RURI scheme is "sips"
by Iñaki Baz Castillo 31 May '11

31 May '11

Hi, "sip:alice@domain.org" is registered in Kamailio. If the proxy receives a request for "sips:alice@domain.org" and invokes "lookup(location)" the function doesn't retrieve the registration of alice. But it should: RFC 5630 section 3.3: When used as the Request-URI of a request, the SIPS scheme signifies that each hop over which the request is forwarded, until the request reaches the SIP entity responsible for the domain portion of the Request-URI, must be secured with TLS; once it reaches the domain in question it is handled in accordance with local security and routing policy, quite possibly using TLS for any last hop to a UAS. When used by the originator of a request (as would be the case if they employed a SIPS URI as the address- of-record of the target), SIPS dictates that the entire request path to the target domain be so secured. Note the last phrase: When used by the originator of a request (as would be the case if they employed a SIPS URI as the address- of-record of the target), SIPS dictates that the entire request path to the target domain be so secured. This is, the entire path *until* the proxy responsible for the domain in the RURI must be secure (TLS) but it's not required (local policy) that the destination proxy dellivers the request to the destination user using TLS. So IMHO lockup(location) should not inspect the registration schema. Am I wrong? -- Iñaki Baz Castillo <ibc(a)aliax.net>

question about module function arguments
by Juha Heinanen 22 Apr '11

22 Apr '11

i understood that module functions can now have an arbitrary number of string, int and pseudo var arguments, where string arguments can possibly also contain pseudo variables. some time ago i asked an example on how this is done, but didn't get any reply. so i'll try again. for example, allow_trusted function is now defined like this: {"allow_trusted", (cmd_function)allow_trusted_2, 2, fixup_pvar_pvar, fixup_free_pvar_pvar, REQUEST_ROUTE | FAILURE_ROUTE}, how can i add a third argument to the function without needing to define yet another fixup_pvar_pvar_something? -- juha

planning release of v3.1.2
by Daniel-Constantin Mierla 08 Feb '11

08 Feb '11

Hello, I think it is time to release v3.1.2, first date that comes in my mind is next Thursday if everyone feels it is enough time to take care of backporting any fix he/she did and it is not yet there. That will provide us a fresh release for the FOSDEM event. If not, then maybe the other week, Tuesday, so the participants at the Kamailio Devel training in Barcelona can practice on it. Soon after we should plan also a release for previous stable, branch 3.0. Anyone having other options? Thanks, Daniel -- Daniel-Constantin Mierla http://www.asipto.com

Hi Kamailio Users, I'm trying to use LCR module in Kamailio 3.1.1 and I', having some problems with this function (load_gws). I'm my kamailio.cfg , I have this route: # SEARCH DEST route[NUMBER] { xlog("L_ALERT", "NUMBER IS $rU \n"); if ($rU=~"^55211020[0-9]{4}$") { # IS MY USERS route(LDAP_NUM2USER); } else { # NOT IS MY USER if (!load_gws(1,$rU)) { xlog("L_ALERT", "LOAD LOCAL GW FAILED $rU \n"); route(DSER); return; } else { xlog("L_ALERT", "LOAD GW DEBUG $avp(i:709)\n"); } ; if (!next_gw()) { xlog("L_ALERT", "NEXT LOCAL GW FAILED\n"); sl_send_reply("503", "Service not available - No gateways"); return; }; setflag(29); route(RELAY); return; }; }; When my call arrive to load_gws, I have this problem: (2198) ERROR: <core> [action.c:1158]: runtime fixup failed for load_gws param 2 (2198) ERROR: <core> [action.c:1511]: run action error at: /etc/kamailio/kamailio.cfg:472 I already saw the Kamailio Code and this error doesn't make sense. Would somebody Help me with it? Very thanks, Thiago Maluf. ---------------------------------------------------------------- Thiago Maluf Resende Tel: +55 21 9700-9113 e-mail: malufrj(a)gmail.com

RPM Packaging Issues
by Martin Hoffmann 31 Jan '11

31 Jan '11

Heisann, the last couple of days, I had the pleasure of building Kamailio 3.1.1 RPMs. Now that the trauma is slowly wearing off, I have two things worth discussing here (or so I believe). One is that I was building for x86_64. In this system, libraries should go into lib64 but module and library directory seem to be hardcoded to lib/$(MAIN_NAME)/ in Makefile.defs. Did I miss the place to switch this or should one be reconsidered? Simply moving the whole /usr/lib/kamailio tree to /usr/lib64/kamailio didn't quite do the trick since the path seems to be embedded in the modules that require some of the shared libraries. Second, there was some fun little breakage with the MySQL module. Because of the way the module's Makefile adds -L directories to the LIBS variable, the linker happily linked against libmysqlclient16.a but somehow forgot to add the libraries that libmysqlclient in turn depends on. I am not quite sure on the mechanics, but presumably libtool takes care of this in the GNU toolchain?[0] In any case, I didn't really want a statically linked MySQL client to begin with. Dropping all the -Ls did that trick. That may or may not be the proper way to do this. I have limited the build to the modules I need or that don't depend on anything funny (this is RHES/Centos, so all you get is Gnome and Firefox and other things very important for servers). Given the time invested so far, I am willing to test my newfound knowledge and give building a full set of packages a try, unless there is dependencies particularly hard to satisfy. I believe Ovidiu has done the RPMs for Centos so far. Maybe we can coordinate work on this? Best regards, Mar"don't you dare saying Debian"tin [0] If the .la files are used also if you don't use the whole automagick, then the reason possibly is that the libmysqlclient16.la that comes with MySQL's own community RPMs is broken since it doesn't list any dependencies. Maybe everything is fine with the MySQL client packages that come with Centos 5. Unfortunately, they date from the late Cambrian or so I have been given to understand.
