destination ip address
by Péter Barabás 12 Jul '16

12 Jul '16

Hi All, i need to store some information in routing_logic script into database with useing SQLOPS module. I made a custom table and store such data like source and destination username, domain, ip address and port. It works fine for almost every parameter except destination IP address and port. I want to ask what is the correct way to determine the destination IP address and port of a user for a MESSAGE, INVITE or BYE message? The $Ri and $Rp is not the correct ones. Thanks.

getting the local 408 response
by Jayesh Nambiar 12 Jul '16

12 Jul '16

Hi, I'm looking to catch the local 408 response generated by kamailio after the fr_timer strikes in. I was assuming to get it in the sl:local-request, but I dont see it in my log messages. I can catch responses like a 200 for register or a 487 for a message who's transaction is not yet created. Any proper way on how do I get to know when kamailio generates a local 408? I'm on the master branch (commit: 54562b873c2c3d0a04f0587e7706188a3eb19a74). Thanks, - Jayesh

Calculating time differences
by Sebastian Damm 11 Jul '16

11 Jul '16

Hi, we are suspending a transaction at one place in our route and resume it later. I want to log the time difference between suspending and resuming. I thought I could do it with saving $TV(Sn), but apparently I can't. Kamailio says, it can't convert the saved value into integer. This true, of course. I was searching for a transformation function converting this string into float, but there is none. Is there any way to calculate a time difference other than to live with seconds-only … [View More]

Kamailio WEBRTC questions/ confusions
by Zaka 10 Jul '16

10 Jul '16

Dear List: I wonder if this has been asked before. Please ignore or point to the appropriate source, if needed. Simply, I have little experience with SIP servlets implementing WEBRTC/ Click2Call etc... Considering a Call Centre scenario offering a WEBRTC solution. Following are the confusions regarding requirements: 1: A Kamailio Box (running WEBSOCKET.config) 2: Customer will use web browser (websocket compatible of course) and enter address of the KAMAILIO Box or we shall need another … [View More]

re-INVITE on IP Change with Outbound
by Colin Morelli 08 Jul '16

08 Jul '16

Hey list, So I'm using the outbound module to ensure subsequent requests are delivered over an active TCP connection established by the mobile client. However, now I'm trying to add support for automatically responding to network changes (WiFi <-> LTE), and it's creating problems. Primarily, the issue is that when the device sends a re-INVITE for the call, its Route: header includes a flow-token corresponding to its *old* socket connection. Because the new request doesn't have the same … [View More]

shtinc throws readonly error
by Sebastian Damm 08 Jul '16

08 Jul '16

Hi, I'm trying to use this line in one route: $shtinc(pushedUsers=>$avp(s:authuser)); However, when checking the syntax of this file, Kamailio says: 0(609) : <core> [cfg.y:3365]: yyerror_at(): parse error in config file /etc/kamailio/kamailio_sip_proxy.cfg, line 3304, column 2-39: read only pvar in assignment left side According to the pseudo vars documentation, I should be able to use it like that. Can someone tell me what I am missing? Best Regards, Sebastian

tsilo ts_append problem
by gmele 08 Jul '16

08 Jul '16

Hello, we are using tsilo to achieve mobile push notification in kamailio. In tsilo module documentation, ts_append() function is used with the pseudo variable “$tU” holding the username of the to-uri. Our config looks like : route[PUSHJOIN] { $var(hjoin) = 0; lock("$tu"); $var(hjoin) = $sht(vtp=>join::$tu); $var(hstored) = $sht(vtp=>stored::$tu); $sht(vtp=>join::$tu) = $null; unlock("$tu"); if ($var(hjoin)==0) { … [View More] if ($var(hstored)) { ts_append("location", "$tU"); } return; } $var(id_index) = $(var(hjoin){s.select,0,:}{s.int}); $var(id_label) = $(var(hjoin){s.select,1,:}{s.int}); t_continue("$var(id_index)", "$var(id_label)", "INVRESUME"); } In ts_append() function code, ts_check_uri() is called on a variable holding a username and not a URI causing the failure of the function ts_check_uri() and resulting in ts_append() to exit. The following line is displayed in the log: [tsilo.c:205]: ts_check_uri(): bad uri [giovanni.mele]. The function ts_store() stores in the R-URI field the username and not the request URI. route[RELAY] { # enable additional event routes for forwarded requests # - serial forking, RTP relaying handling, a.s.o. if (is_method("INVITE|BYE|SUBSCRIBE|UPDATE")) { if(!t_is_set("branch_route")) t_on_branch("MANAGE_BRANCH"); } if (is_method("INVITE|SUBSCRIBE|UPDATE")) { if(!t_is_set("onreply_route")) t_on_reply("MANAGE_REPLY"); } if (is_method("INVITE")) { if(!t_is_set("failure_route")) t_on_failure("MANAGE_FAILURE"); } if (!t_relay(PROXY_IP, PROXY_PORT)) { sl_reply_error(); } if (is_method("INVITE")) { ts_store(); $sht(vtp=>stored::$tu) = 1; route(SENDPUSH); } exit; } route[INVRESUME] { statsd_gauge("SIPRegistrar.InviteResumed", "+1"); lookup("location"); t_relay(PROXY_IP, PROXY_PORT); ts_store(); $sht(vtp=>stored::$tu) = 1; } With the command “kamcmd ts.dump” we can see the following lines: R-URIs: { R-URI: giovanni.mele Hash: 74014921 Transactions: { Transaction: { Tindex: 63704 Tlabel: 2105932514 } } } If we try to use the ts_append() function with the pseudo variable “$tu” holding the full to-uri address, there is no error returned by ts_check_uri() (as this is called on a correct URI) but the transaction corresponding to the to-uri cannot be found (maybe because the R-URI stored by ts_store() is the username and not the full R-URI). How can we make things work ? By storing the full R-URI with ts_store() ? Thx for your help Giovanni -- View this message in context: http://sip-router.1086192.n5.nabble.com/tsilo-ts-append-problem-tp150184.ht… Sent from the Users mailing list archive at Nabble.com.

4.4.1: Only first UDP Listener is producing log messages
by Sebastian Damm 08 Jul '16

08 Jul '16

Hi, I upgraded one of our systems today to 4.4.1. And when checking whether everything is okay, I noticed, that only the first UDP listener (from kamcmd core.ps) is actually sending lines to the log. The only other logs I see are from usrloc timer worker. kamcmd> core.ps 10737 main process - attendant 10740 udp receiver child=0 sock=172.20.40.5:5060 10741 udp receiver child=1 sock=172.20.40.5:5060 10742 udp receiver child=2 sock=172.20.40.5:5060 10743 udp receiver child=3 sock=172.20.40.5:… [View More]
