by VOIP Tests 20 May '14

20 May '14

Hello, I understand that there are some bugs in ver 4.03. Can someone let me know how I can update my running version of Kamailio ( 4.03 ) to version 4.1? Will I need to do a fresh install of the new version or is there a way I can do an upgrade/update to ver 4.03? Thank you, Arun

[rtpengine] No media from WebRTC UA
by Alexey Rybalko 20 May '14

20 May '14

Hello! During a call from classical SIP softphone to WebRTC there's no media from the browser (Mozilla, the same result is for Chrome). In case of a call from the browser to the softphone there's media flow from both sides. The snippets from kamailio.cfg related to the problem case (SIP-->WebRTC) are below. OFFER: $var(rtpp_flags) = "trust-address symmetric replace-origin replace-session-connection"; $var(rtpp_flags) = $var(rtpp_flags) + " ICE=force"; $var(rtpp_flags) = $var(rtpp_flags) + " RTP/SAVPF"; rtpengine_offer($var(rtpp_flags)); ANSWER: $var(rtpp_flags) = "trust-address symmetric replace-origin replace-session-connection"; $var(rtpp_flags) = $var(rtpp_flags) + " ICE=remove"; $var(rtpp_flags) = $var(rtpp_flags) + " RTP/AVP"; rtp.log is attached. Any help on this issue would be very appreciated. with best regards, Alexey

code review tools
by Daniel-Constantin Mierla 20 May '14

20 May '14

Hello, some time ago it was proposed to use a code review tool to analyze patches, the topic was also discussed during the last IRC devel meeting. I cc-ed users mailing list, because people there might have experiences with some of them. I found on wikipedia a short list of available applications for this purpose: - http://en.wikipedia.org/wiki/List_of_tools_for_code_review Personally I haven't used any so far. Iirc, gerrit was proposed before by Victor Seva. From the wikipedia list, Differential would be straightforward to deploy from dependencies point of view, as we have php on our servers. But I have no clue which is the right/best to use, so here we have to decide if worth to use one and which one. Besides the above one, perhaps github has an integrated review tool. I can be considered as an alternative as well. My opinion is that such tool is useful, specially for big patches, to allow easier more people to have a look at them. Hoping to get feedback on benefits of such tools and which would be the right/best to use. Cheers, Daniel -- Daniel-Constantin Mierla - http://www.asipto.com http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda

failed to find command redis_cmd
by Ryan Brindley 20 May '14

20 May '14

Hey Community, I'm trying to play around with ndb_redis, but seem to be missing something probably obvious as I'm getting a "failed to find command redis_cmd" error on load. loadmodule "ndb_redis.so" modparam("ndb_redis", "server", "name=test;addr=127.0.0.1;port=7000") request_route { redis_cmd("test", "SET foo bar", "r"); } I've verified that mpath = /usr/local/lib64/kamailio/modules/ and that ndb_redis.so is in that directory. Any help is greatly appreciated. Ryan Brindley

cfg values read from Database possible?
by Daniel Vukicevic 19 May '14

19 May '14

kamailio -V version: kamailio 3.2.2 (x86_64/linux) I am setting different cfg Parameters via XMLRPC. Which is good for changing parameters per runtime and being independent from database lookups when kamailio is running. Unfortunately cfg settings will be lost and empty after Restarting Kamailio if cfg values aren’t set before the request_route. So the idea was to look if cfg value is set, if not look into database and take the last cfg setting which was set. (Last cfg values will updated via SQL Query in the XMLRPC branch). # check if abc.test is defined if (strempty($sel(cfg_get.abc.test))) { sql_xquery("ca", "SELECT * from cfg where abc=‚test'", "ra“); The problem is that it seems, that there is no way to read out the values from database and to set the cfg variable again when kamailio is starting, because there is no way to inject cfg values into kamailio, when kamailio is already started. Here i need something like this: abc.test = "$xavp(ra=>LB01)" desc „TEST“; <<which doesn’t work in this form. (just to make it clear what i want) I found http://kamailio.org/docs/modules/stable/modules/cfg_db.html , but documentation is quite bad. Are there any other possibilities for me? The only way it might work for me (which is in my opinion quite dirty), to exec_dset an external command and to inject the new cfg via XMLRPC. The new cfg value is updated into database via XMLRPC again (which works, just for the sake of completeness): #!ifdef WITH_XMLRPC route[XMLRPC] { … … # Keeping values for Kamailio Restart sql_query("ca", "UPDATE cfg set LB01='$sel(cfg_get.abc.test)' where abc=‚test‘"); Mabye of one of you guys have a hint for me to solve this problem? Cheers Daniel

Rtpproxy ptime in ringing inject
by Grygoriy Dobrovolskyy 19 May '14

19 May '14

Hello list, a long time ago i have build and application which injects ringing from rtpproxy to the client, while i am trying to reach his destination. The commande looks like this (log) May 19 10:17:44 rtpproxy[2529]: DBUG:handle_command: received command "29304_278705 P-1 B2B.256.470174 /usr/local/src/rtpproxy/sounds/ring session d20fbd749deed7e1f54460af276dee6d-0ead;1 " May 19 10:17:44 rtpproxy[2529]: INFO:handle_play: -1 times playing prompt /usr/local/src/rtpproxy/sounds/ring codec 8 May 19 10:17:44 rtpproxy[2529]: DBUG:doreply: sending reply "29304_278705 0#012" Everything works fine, a long time ago i have modded the rtpproxy a bit so when he sends the audio, he sends it with 20ms ptime instead of default 10ms, and i have totally forgot where is that part, i am digging into sources and not able to find it. Dear list if somebody remembers where is this damn setting in sources, i would be glad to hear from you. Thank you

mtree reload commands don't remove items from memory
by Juha Heinanen 18 May '14

18 May '14

i started to wonder why routing was sometimes wrong in my proxy and after studying the issue, i came to the conclusion that mtree reload commands (mi or rpc) don't remove entries from memory when they are removed from database. i started my proxy with empty mtrees db table (and empty memory table): # sip-proxy_ctl mi mt_summary MT:: TNAME=lp_out TTYPE=0 MEMSIZE=0 NRNODES=0 NRITEMS=0 RELOADCOUNT=0 RELOADTIME=1400419785 then i added one entry to db table and gave reload command. after that one entry correctly showed up in memory table: # sip-proxy_ctl mi mt_summary MT:: TNAME=lp_out TTYPE=0 MEMSIZE=1636 NRNODES=6 NRITEMS=1 RELOADCOUNT=1 RELOADTIME=1400419817 then i deleted the only entry from db, verified with phpmyadmin that the table really was empty, and gave again reload command. that command didn't have any effect in memory table: # sip-proxy_ctl mi mt_summary MT:: TNAME=lp_out TTYPE=0 MEMSIZE=1636 NRNODES=6 NRITEMS=1 RELOADCOUNT=1 RELOADTIME=1400419817 not even reload count got incremented. after that i went and added some debug to rpc_mtree_reload function and got this: May 18 16:30:17 siika /usr/sbin/sip-proxy[26536]: INFO: mtree [mtree_mod.c:1169]: rpc_mtree_reload(): reloading from db 'lp_out' the info is here: LM_INFO("reloading from db '%.*s'\n", pt->tname.len, pt->tname.s); if(mt_load_db(pt)!=0) { LM_ERR("cannot re-load mtree from database\n"); goto error; } my conclusion is that mt_load_db() function is somehow broken. -- juha
