[SR-Users] Media Proxy and STUN
Hi All, After reading the docs I got that it is possible to configure the server so it will change the SDP so clients will send the media to the media proxy. But, what if the clients are not behind a symmetric NAT and using ICE where able to get their real IP:port? How can the server be aware to this and not change the SDP?

[SR-Users] Timer Process versus Slow Timer Process
Hi All, I'm looking to have a better understanding of when to use the Timer process versus the Slow Timer Process. This is what I came up with, but please correct me: - The “*Timer*” process is used to handle core processing within Kamailio. Therefore, you don’t want to put long running logic into the routing handler - The “*Slow Timer*” process can be used for long running processes ___ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
Re: [SR-Users] Kamailio authentication method
Hello, On 07/05/15 15:38, Mathys Frédéric wrote: Still on the subject, we are exploring the possibilities and one of them would be to use the diameter module. As stated in the documentation : “NOTE: diameter support was developed for DISC (DIameter Server Client project at http://developer.berlios.de/projects/disc/). This project seems to be no longer maintained and DIAMETER specifications were updated in the meantime. Thus, the module is obsolete and needs rework to be usable with opendiameter or other DIAMETER servers.” Is it planned to update this module on your side on not? the module might be (pretty) functional, but due to no real demand and lack of open source diameter servers, it was not proper maintained. Note that there is another module that does diameter, named cdp, which is mainly used in IMS deployments -- this one is active and used. One other solution would be to write our own module to connect to another server (which contains the users/passwords and calculate the HA1 and HA2 values), tcp layer would still be done by auth module. To do that, is there a spec on how to communicate with auth module? And any documentation on custom module development and deployment? The principle would be more or less the same as diameter, but maybe our server would not use radius nor diameter protocols. Maybe for this case is better to use http to contact the server -- you can do an http query from kamailio.cfg using utils module (another module for http operations should be in a personal branch of Olle, something related to curl -- see all branches in our git repository). Also, you may build a faster prototype using an embedded language (Lua, Perl, Python -- see the modules that have the name starting with app_ ). By doing it, we try to reach two goals : use SHA instead of MD5 and increase the security of the user management by hosting it in a different way as Kamailio does. Said in a previous email -- you can focus on auth module for pv_auth_check() function. You can fetch the password or its hashed variant via other connectors (e.g., ldap, sqlops) -- see next a tutorial about ldap: - http://www.kamailio.org/wiki/tutorials/mini-howto-admin/ldap-user-auth Cheers, Daniel Thank you, Frederic *From:*sr-users [mailto:sr-users-boun...@lists.sip-router.org] *On Behalf Of *Daniel-Constantin Mierla *Sent:* Wednesday 6 May 2015 16:44 *To:* Kamailio (SER) - Users Mailing List *Subject:* Re: [SR-Users] Kamailio authentication method Hello, to understand properly, do you need to have: HA1=SHA(username:realm:password) HA2=SHA(method:digestURI) response=SHA(HA1:nonce:HA2) Perhaps it can be done with config file scripting, if you are familiar with transformations and header manipulation.

Modification of the auth module seems to be a better solution, but this lead to some questions for me… - Could you explain a little bit how the auth module is working? Which files do I have to modify to change the hash method? It is hard to remember by heart or explain here -- but in short, what I would do is to identify where the MD5 hashing is done and from there try to add an alternative for shaX. - If I used another auth_* module to get username / password, the modification in the auth module is enough for the www_authentication? In other words, the authentication is always done in this module? Even If I use auth_radius or auth_diameter or a self-made auth_* module? Some of those modules might be touched as well, given, for example, that auth_db can already retrieve the hashed value from the database.

Re: [SR-Users] db_text error
Yes, it seems it is looking for different database path -- can you double check to be sure you set db_url properly for all modules?

[SR-Users] Memory leak or bad setting.
Hello We experienced a failure on our kamailio (4.2.1+trusty), which required a restart. May 6 07:40:41 rtpproxy01 /usr/sbin/kamailio[5467]: ERROR: core [msg_translator.c:2270]: generate_res_buf_from_sip_res(): out of mem Afterwards we inspected all the settings to be using default, but at a much higher level than an other older kamailio which runs much more traffic. The big difference, is that this kamailio works with rtpengine. Does that require more memory? We also observed that the free memory is constantly falling on some instances. They all started with 16MB but after 1½ day some are on 11.6 Is this normal behaviour that will find a natural level or is there something bad going on? We can also see that there are frags. Is that to be worried about, or is this natural? kamcmd pkg.stats | egrep -e 'free|frag' free: 16362760 total_frags: 17 free: 15835176 total_frags: 232 free: 15845760 total_frags: 205 free: 15829288 total_frags: 188 free: 15847456 total_frags: 181 free: 15853024 total_frags: 183 free: 15873232 total_frags: 225 free: 15858584 total_frags: 231 free: 15834592 total_frags: 205 free: 15852520 total_frags: 132 free: 15869048 total_frags: 120 free: 15824872 total_frags: 100 free: 15828448 total_frags: 113 free: 15858216 total_frags: 109 free: 15861992 total_frags: 82 free: 15871712 total_frags: 110 free: 15813824 total_frags: 109 free: 11583736 total_frags: 121 free: 11588896 total_frags: 106 free: 11580448 total_frags: 118 free: 11586312 total_frags: 134 free: 11592840 total_frags: 159 free: 11632536 total_frags: 120 free: 11582368 total_frags: 127 free: 11660104 total_frags: 97 free: 16352192 total_frags: 14 free: 16351088 total_frags: 13 free: 16341248 total_frags: 46 free: 16351184 total_frags: 19 We use 4.2.1+trusty with these modules, is it possible that a newer version has fixed some memory leak? loadmodule db_mysql.so loadmodule mi_fifo.so loadmodule kex.so loadmodule tm.so loadmodule tmx.so loadmodule sl.so loadmodule rr.so loadmodule pv.so loadmodule maxfwd.so loadmodule textops.so loadmodule siputils.so loadmodule xlog.so loadmodule sanity.so loadmodule ctl.so loadmodule mi_rpc.so loadmodule acc.so loadmodule dispatcher.so loadmodule permissions.so loadmodule sdpops.so loadmodule rtpengine.so -- Med venlig hilsen / Best regards Kjeld Flarup (Christensen) M.Sc E.E, Teknisk chef Viptel ApS, Benslehøjvej 3, DK-7470 Karup J Telefon: +45 46949949, Telefax: +45 46949950, http://viptel.dk ___ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
Re: [SR-Users] Recommended configuration for TCP support
What would happen in this case? If I understand correctly, the proxy will always forward the request but the last hop (before the UAS) will forward the request only if a connection is active? correct. If the last hop doesn't forward the request because no TCP connection exists, what happens? How the proxy will detect this situation? It won't find any matching connection and won't try to establish a new one since you asked it to not. So it will just send a reply back to the registrar with an error. After receiving an error registrar in its turn can perform some smart actions like forwarding to a voicemail system. ___ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
