[Kamailio-Users] is_present_hf function
by Antonio Reale 10 Dec '08

10 Dec '08

Hi all, I have a problem with the is_present_hf function from TEXTOPS module. In the script (openser 1.2.3-notls) I have: --- if(is_present_hf("Proxy-Authorization")) { xlog("L_ERR", "Proxy-Authorization header present\n"); consume_credentials(); } --- When the proxy receives the BYE message I see in the log: Dec 10 16:00:54 sipsvr /usr/sbin/openser[12846]: Proxy-Authorization header present Dec 10 16:00:54 sipsvr /usr/sbin/openser[12846]: consume_credentials(): No authorized credentials found (error in scripts) Tracing the call I don't see any Proxy-Authorization header in the BYE message. Why the function is_present_hf returns true? Attached you will find debug messages from Openser/Kamailio and the BYE. I see the problem using Kapanga softphone, but the same problem occurs in production environment with different CPEs (for instance Linksys SPA2102). The strange thing is that it occurs only when kapanga is the caller (and hungup) and not when it is the callee (and hungup). Using wireshark I see that the BYE is the same in both situation. How can I debug this problem? Thanks a lot. Regards, Antonio.

[Serusers] Issue with auth_identity
by jerome.herve＠orange-ftgroup.com 10 Dec '08

10 Dec '08

Hello, I am trying to put in place auth_identity between 2 SER proxies and it doesn't work well. The first one manages to add identity and identity_info fields and to send the INVITE to the other proxy. But when the other proxy receive the message and does his tests there is an issue. It sends back a 436 Bad Identity Info. The error happens during the "vrfy_get_certificate" function (function which downloads the certificate thanks to identity_info URL). On my proxy logs, I can see this : AUTH_IDENTITY:retrieve_x509: DER Certificate error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag I really don't know what to do, do you have any idea? Thanks, Regards, Jérôme HERVE

by Henning Westerholt 10 Dec '08

Hi, according to our last IRC meeting [1] we want to release a minor release for the 1.4 branch in the next days. We've did already over 40 changes in this branch, many of them for important bugs, so i propose the next thursday, the 11th december as the date for 1.4.3. So if you have any important backports or other fixes that should go into this release, please commit them until this day. While already on the release topic, the code freeze period for the 1.5.0 release will be start in the mid of Januar, roughly in about 6 weeks from now. So if you like to contribute something that should be included in this release, please commit it to our repository or upload the patch to the tracker for review. Already finished features and the roadmap can be found as usual in our wiki at [2, 3]. If you like to give the new features a try, then you find prebuild packages for several debian releases here [4]. Please report any bugs you find to our developer list. Best regards, Henning [1] http://www.kamailio.org/mos/view/News/NewsItem/IRC-Devel-Meeting-Summary---… [2] http://www.kamailio.org/dokuwiki/doku.php/features:new-in-1.5.x [3] http://www.kamailio.org/dokuwiki/doku.php/roadmap:1.5.x [4] devel.kamailio.org

[Kamailio-Users] important: gflags, options, uri module functionality moved
by Henning Westerholt 09 Dec '08

09 Dec '08

Hi, in order to reduce the number of modules that needs to be maintained we integrated several small modules into existing ones. This applies only to the devel (trunk) version. No functionality was removed, it can be now just found in a different place. 1. gflags module The functionality of this module was integrated into the cfgutils module. The internal functionality, function names and MI commands are the same, the parameter “initial” was renamed to “initial_gflags”. 2. options module The functionality of this module was integrated into the siputils module. The function name was not changed, all parameters were prefixed with the "options_” string. 3. uri module The functionality of this module was integrated into the siputils module. The function names were not changed, internal functionality is the same. So starting from the release 1.5 you'll need to fix your "loadmodule" statements and some parameter prefixes in your config if you use one of the mentioned modules. Documentation for the functions can be found in the usual place [1, 2]. Cheers, Henning [1] http://www.kamailio.org/docs/modules/devel/cfgutils.html [2] http://www.kamailio.org/docs/modules/devel/siputils.html

[Kamailio-Users] no free tcp receiver
by Gawith 09 Dec '08

09 Dec '08

Hi all, My OpenSER system seems to run out of TCP handlers all the time. It looks to me that I need two child processes for each local IP and peer combination, because to and back communication do not use the same TCP channel. I have a lot of TCP clients which would lead to more than 100 child processes. Does it make sense to reduce tcp_connection_lifetime? This would increase TCP overhead, but would allow me to have fewer child processes, right? Any help is welcome. Thanks guys! Regards

[Kamailio-Users] Xcap-diff publishing?
by John Stalh 09 Dec '08

09 Dec '08

Hello, I am trying to setup Kamailio to publish xcap-diff payload to a client. However, the xcap-diff event is not supported (receives a SIP 489 answer), even though it says Kamailio supports it. What am I missing? How does the mi_xmlrpc module works? For reference, I use Openxcap and it is correctly (theorically at least) set to use Kamailio. Best regards, John

[Kamailio-Users] new features: $T_req(pv) and $T_rpl(pv)
by Daniel-Constantin Mierla 09 Dec '08

09 Dec '08

Hello, the TM module introduces two new features: - access to SIP request attributes while processing a reply belonging to same transaction - access to SIP reply attributes while processing a request belonging to same transaction Functionalities come as pseudo-variables, $T_req(pv) and $T_rpl(pv) - where pv can be any pseudo-variable, check documents at: http://www.kamailio.org/dokuwiki/doku.php/pseudovariables:devel#tm_module_p… The new pseudo-variables can be used: - in failure_route to get the attributes of the reply causing the failure route. You can take decisions what to do with the request based on reply details - in onreply_route to get the attributes of the request. you can take decision what to do with the reply based on request attributes. - in acc to store data from reply - in C code (modules) Note that couple of PV are disabled for these cases (PV will return null) - these are the PV that alter/depend on the context of the processed message, like $Ts, $Tf (but you can use $TS and $TF), $time, destination set attributes. The $avp() will be current avps, as they are stored in a global list. Also, in case there is a timeout or other reply generated by kamailio itself, $T_rpl(pv) will return null as there is no real reply structure behind. Example, print the source ip of the reply in failure route: failure_route[1] { xlog("reply received from: $T_rpl($si)\n"); } Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com

In my small Linux experience, when I tar xvf... something.tar.gz a directory of something is created and then I usually can find the makefile there. Why I can't find it now? I'm trying to follow the instructions on http://www.kamailio.org/mos/view/Installation-Notes/ but I can't do it. Can anyone please give some suggestions? Thanks in advance, Juan.-
