Next Kamailio IRC Devel Meeting, Apr 20, 2016
by Daniel-Constantin Mierla 21 Apr '16

21 Apr '16

Hello, I am proposing a new IRC meeting to discuss the current major issues and the plans for next Kamailio release, on Wednesday, April 20, 2016, with alternative for next day, April 21. If many developers are not available, we can postpone it to another date in the near future (make proposals if that is the case for you). I created a wiki page for it: * https://www.kamailio.org/wiki/devel/irc-meetings/2016a Add there the topics that you want to be discussed. Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda Kamailio World Conference, Berlin, May 18-20, 2016 - http://www.kamailioworld.com

DMQ_USRLOC sync CSEQ error
by José Seabra 21 Apr '16

21 Apr '16

Hi There, I'm using dmq and dmq_usrloc between 2 kamailio(version 4.4.0) registrar servers. I'm registering 15000 subscribers with sipp and everything is ok, the registration address of record are shared between both registrar servers. The problem here is when I restart one of the registrar server and then the other registrar server starts synchronization to restarted server. The error that i see on this process is the following shown bellow: ERROR: dmq_usrloc [usrloc_sync.c:75]: add_contact(): Invalid cseq But all the contacts are synchronized, what can cause this error? and what is the impact on normal behavior of kamailio? Best regards -- José Seabra

kazoo database not bound error
by Jayesh Nambiar 21 Apr '16

21 Apr '16

Hello, Using kazoo only to connect to amqp gives an error if the db_url is not specified. If db_url is specified it tries to do presence related stuff even if not intended. The solution was to use: modparam("kazoo", "pua_mode", 0) which I found here: http://lists.sip-router.org/pipermail/sr-users/2015-September/090092.html This is not documented in the kazoo module. Would be great if this is added in the module documentation to simplify the use of module. Thanks, - Jayesh

A: Kamailio World 2016 - Four Weeks Before
by Daniel-Constantin Mierla 20 Apr '16

20 Apr '16

Time is passing and Kamailio World Conference 2016 is approaching at fast pace – only four weeks left till the start of the event! The schedule [1] is pretty much nailed down, with some adjustments still expected to happen. The event starts like the past edition with a half a day of technical workshops, followed by two full conference days. A larger group of speakers [2] is participating to this edition. There was a big number of speaking proposals and we wanted to highlight more of the people that had a relevant contribution to the evolution of the project. To accommodate properly, two more discussion panels were added, keeping also the classic VUC panel. The topics cover many of the interesting aspects of real time communications, from security and scalability to WebRTC and VoLTE, touching Kamailio and other open source projects like Asterisk or FreeSwitch. More details can be found on the website of the event: - https://www.kamailioworld.com Don’t forget that this year Kamailio celebrates 15 years of development, the party is at Kamailio World! We expect to fill the capacity of the conference room, if you haven’t registered yet and plan to attend, do it as soon as possible to secure your seat! [3] Many thanks to our sponsors [4] that made possible this event: FhG Fokus, Asipto, Sipwise, Matrix.org, Sipgate, Simwood, NG Voice, Digium, VoiceTel, Evariste Systems, Core Network Dynamics, Pascom, Didx.net. Thank you for flying Kamailio and looking forward to meeting many of you at Kamailio World 2016!

another bug with JSONRPC-S?
by Brooks Bridges 20 Apr '16

20 Apr '16

I may have stumbled across another bug with this module. I believe the htable.dump method isn't correctly recognizing that a table name is being provided: [root@server ~]# curl -s --header 'Content-Type: application/json' --data-binary '{"jsonrpc": "2.0", "method": "htable.dump", "name": "callstats"}' http://1.2.3.4:5060/jsonrpc {"jsonrpc":"2.0","error":{"code":-32000,"message":"Execution Error"}} Debug log: 2016-04-19T17:42:30.046892+00:00 server /usr/local/sbin/kamailio[21634]: DEBUG: <core> [tcp_main.c:2465]: tcpconn_do_send(): buf=#012HTTP/1.1 500 No htable name given#015#012Sia: SIP/2.0/TCP 1.2.3.4:54912#015#012Content-Type: application/json#015#012Server: kamailio (4.4.0-rc1 (x86_64/linux))#015#012Content-Length: 69#015#012#015#012{"jsonrpc":"2.0","error":{"code":-32000,"message":"Execution Error"}} Brooks Bridges | Sr. Voice Services Engineer O1 Communications 5190 Golden Foothill Pkwy El Dorado Hills, CA 95762 office: 916.235.2097 | main: 888.444.1111, Option 2 email: bbridges(a)o1.com<mailto:bbridges@o1.com> | web: www.o1.com<http://www.o1.com/>

$shtval(htable=>key)

What is this? It's referenced here: http://kamailio.org/docs/modules/stable/modules/htable.html#idp1912904 but I cannot find it anywhere else. The only 2 places I find any reference to it at all in the entire codebase is here: modules/htable/doc/htable_admin.xml: <emphasis>$shtval(htable=>key)</emphasis> modules/htable/README: * $shtval(htable=>key) Brooks Bridges | Sr. Voice Services Engineer O1 Communications 5190 Golden Foothill Pkwy El Dorado Hills, CA 95762 office: 916.235.2097 | main: 888.444.1111, Option 2 email: bbridges(a)o1.com<mailto:bbridges@o1.com> | web: www.o1.com<http://www.o1.com/>

Kamailio Blind Call Forwarding
by Nagorny, Dimitry 19 Apr '16

19 Apr '16

Hi all, I'm trying to make a blind call forward to "1002" if a UA calls "1" into Kamailio. At the moment I have the following config: if ( $rU=~"^[1]$" && src_ip==$sel(cfg_get.pstn.gw_ip) ) { sl_send_reply("181", "Redirecting"); $ru = "sip:1002@" + $sel(cfg_get.pstn.gw_ip) + ":" + $sel(cfg_get.pstn.gw_port) + ";user=phone"; force_send_socket(udp:MY_EXTERN_IP:5060); route(NORMAL_RELAY); #Just t_on_branch/reply/failure if (!t_relay()) { sl_reply_error(); } exit; } The calling UA is from the PSTN as well as the called UA. Problem right now is that the PSTN's anti-Loop protection jumps in and rejects the INVITE to 1002. Question: Is it possible to tell the calling UA "Hey wait, 181..." with Kamailio, then build seperately an independent Call Leg (with new CallID?) from Kamailio to UA "1002" and finally to put them together? Any help is very much appreciated even if they are just guides/examples. I'm using Kamailio 4.3.5 on CentOS 7.2. Very Respectfully Dimitry Nagorny Trainee
