Wrong Call-ID and tags in response to OPTIONS
by Jean-Marie Baran 10 Aug '15

10 Aug '15

Hi, I am trying to get Kamailio working with a third party SIP provider. This provider pings Kamailio with OPTIONS messages, but Kamailio does not answer correctly: the Call-ID and the tags change where they should not. Here is an example: Third party SIP server: OPTIONS sip:false.sip.provider:5060 SIP/2.0 Via: SIP/2.0/UDP 197.17.144.4:5060;branch=z9hG4bK8e45ac1463a From: <sip:197.17.144.4>;tag=1669836943 To: <sip:false.sip.provider> Date: Fri, 07 Aug 2015 12:34:37 GMT Call-ID: a012e080-5c41a5ce-8e5-38512c6(a)197.17.144.4 User-Agent: Cisco-CUCM10.5 CSeq: 101 OPTIONS Contact: <sip:197.17.144.4:5060> Max-Forwards: 0 Content-Length: 0 Kamailio's answer: SIP/2.0 200 OK Via: SIP/2.0/UDP 197.17.144.4:5060;branch=z9hG4bK93e5f072f5f;received=174.37.217.1 From: <sip:197.17.144.4>;tag=298911055 To: <sip:false.sip.provider>;tag=b27e1a1d33761e85846fc98f5f3a7e58.8c24 Call-ID: 2defcb00-5c41aa17-93f-38512c6(a)197.17.144.4 CSeq: 101 OPTIONS Server: kamailio (4.3.1 (x86_64/linux)) Content-Length: 0 You can see that the Call-ID change from "a012e080-5c41a5ce-8e5-38512c6" to "2defcb00-5c41aa17-93f-38512c6". Likewise, the From tag change ("1669836943" to "298911055"). What could be the reason for this ? Moreover I think Kamailio should add the field Allow (with INVITE,ACK,BYE,CANCEL,INFO,OPTIONS,REFER,SUBSCRIBE,NOTIFY), but it does not. I should mention that I had to modify /kamailio.cfg/ to have Kamailio answer to OPTIONS messages (I added *the code in bold*): if (*!is_method("OPTIONS") && *!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; } if(is_method("OPTIONS") && uri==myself && $rU==$null) { *#* sl_send_reply("200","Keepalive"); *options_reply();* exit; } Maybe this hack replaces an expected behavior that I failed to see/configure ? Thanks, Jean-Marie.

Hi is there any way to achive following usecase using carrier route / LCR / droude module i have 10 different termination gateways, each gateways will have more than 10000 destinations and each gateways will have different rate, for example 91 Destination ( there will be 10000 entries like 91 ) gw1 gw2 gw3 gw4 gw5 0.001 0.007 0.003 0.002 0.003 now need to logic to load the these destination with cost and sort gateways in order of longest match of dialled number,cost, priority for the dialled destination, which will not use too much CPU and memory Regards Arun

Kamailio crash when imc_list_rooms
by SamyGo 09 Aug '15

09 Aug '15

Hi, I'm working with IMC module and noticed that when I execute fifo command "imc_list_rooms" it crashes. [root@kamailio75 ]# kamctl fifo imc_list_rooms my Kamailio version is 4.2.1 Right now the way IMC module works is that a SIP UA has to send a chat room command to create a new room, get participants added etc. If I try to add users directly from DB the kamailio don't recognize the room or participants unless restart. Would it be possible to reload the DB tables for IMC via MI command, a big plus if we can do room creation, user addition via MI as well ! Thanks, Sammy

acc Module missing BYE in database
by Dirk Teurlings - SIGNET B.V. 07 Aug '15

07 Aug '15

Hi again, Running kamailio 4.2.5 with the acc module to do accounting in a MySQL database. We are now running into the issue that sometimes there is no BYE line when there is an INVITE. Digging into this I noticed that the dialog:end event does get triggered, and that CNXCC consumes the call properly. So the BYE message does get sent, but acc doesn't seem to pick it up some of the times. It occurs around maybe once every 100 calls. Anybody got any ideas about this? -- Cheers, Dirk Teurlings

Kamailio example trace needed UAR/UAA
by Jan Devai 07 Aug '15

07 Aug '15

Hi Experts, we have trouble with the last SIP Registration from I-CSCF to S-CSCF, see below: *The flow is as follows:* UE HSS P-CSCF I-CSCF S-CSCF -----------Sip Register-----------> -------Sip Register-------> <--------------------------UAR--------------- --------------------------UAA---------------> ----SIP Register---> Almost a week ago, I've open a thread about this issue called "Error forwarding to SCSCF", and so far we did not get any further with it :-( I was wondering does somebody have similar Signaling that he could share with us? It could be either with an external or OpenHSS, does not matter at this stage. It would definitely move us forward with at least the signaling comparison as a start point. Maybe the UAA answer and anything happening before is wrong. Any reference, similar working trace would be greatly appreciated. Thank you in advance Jan

SDP IPv4 has been concatenate - no audio
by Loic Chabert 07 Aug '15

07 Aug '15

Hello everyone, I'm trying put kamailio in front of asterisk server farm. Fow now, 2 asterisk servers are running and i'm trying to make some basic calls between two UACc. All asterisk servers has been ofuscaded from public internet using 10.189.122.0/24 network. All trafic must be passed throught asterisk so RTPproxy is used to (and used for rtp bridging). Kamailio and rtpproxy is running with public IP address, and private ip address (mhomed=1) But a wired thing append on my SDP body: c line have two rtpproxy public addresses concatenate (see my capture attached). Any reason for this ? Only invite method from my asterisk contains 2 publics IP addresses concatenated. Does it mean than rtp_manage as been executed twice ? Thanks in advance. Regards.

Problem adding json module
by Joao Alves 07 Aug '15

07 Aug '15

Hi, Have just installed the kamailio 4.3 (from github) and was trying to include the additional modules that I require. I've edited the modules.lst and changed the extra modules to compile "include_modules= db_mysql utils json". During compilation (using "make all") getting the following warnings in relation with the json module. CC (gcc) [M json.so] json_funcs.o json_funcs.c: In function 'json_get_field': json_funcs.c:58:2: warning: implicit declaration of function 'is_error' [-Wimplicit-function-declaration] json_funcs.c:64:2: warning: 'json_object_object_get' is deprecated (declared at /usr/local/include/json-c/json_object.h:303) [-Wdeprecated-declarations] And later, when running the config file: ERROR: <core> [sr_module.c:574]: load_module(): could not open module </usr/local/lib64/kamailio/modules/json.so>: libjson-c.so.3: cannot open shared object file: No such file or directory 0(2344) : <core> [cfg.y:3432]: yyerror_at(): parse error in config file /usr/local/etc/kamailio/kamailio.cfg, line 195, column 12-20: failed to load module ERROR: bad config file (1 errors) I have already installed json-c modules and confirmed this installation by doing: root@ID14337:/usr/local/kamailio-4.3/kamailio# pkg-config --cflags json-c -I/usr/local/include/json-c root@ID14337:/usr/local/kamailio-4.3/kamailio# pkg-config --libs json-c -L/usr/local/lib -ljson-c root@ID14337:/usr/local/include/json-c# ls arraylist.h json.h json_inttypes.h json_object_private.h linkhash.h bits.h json_c_version.h json_object.h json_tokener.h printbuf.h debug.h json_config.h json_object_iterator.h json_util.h random_seed.h root@ID14337:/usr/local/include/json-c# cd ../../lib root@ID14337:/usr/local/lib# ls libjson-c.a libjson-c.la libjson-c.so libjson-c.so.3 libjson-c.so.3.0.0 pkgconfig python2.6 python2.7 root@ID14337:/usr/local/lib# So any ideas of what could be causing this to fail?

Kamailio w/ external routing server
by Eric Babcock 07 Aug '15

07 Aug '15

Hey Everyone, I've been banging my head against the desk for days trying to get this working, and I'm sure it's something simple that I'm not doing, but maybe someone else can add some input. Here is the best way to describe my call flow. Customer -> Kamailio -> Routing Server (302) -> Kamailio -> Vendors (from the 302 header) I have tried to configure dispatch, but that hasn't worked out for me. My routing server does the authentication, LRN lookup, and provides the vendor routes in the sip header. So when I pass the call to the routing server, it has to contain the customer information. This setup has to be stateful so I can write CDRs for billing to MySQL. The reason I tried using dispatch, is because I have multiple routing servers I would like to load balance across or even failover if one goes down. Can anyone help me out, or at least help point me in the right direction? Thanks! -Eric -- View this message in context: http://sip-router.1086192.n5.nabble.com/Kamailio-w-external-routing-server-… Sent from the Users mailing list archive at Nabble.com.
